Unknown IP Address Range On Router DHCP Client List
Nov 19, 2011
I keep getting some additional IP addresses logging onto my home network that have an address outside what should be allowed by the router. The server is running at 192.168.2.1 and is set to only allow clients from 192.168.2.2 - 192.168.2.10 so a total of 9 clients should be allowed on.The problem is that something keeps logging in with an address of 192.168.169.2 or 3 etc. Sometimes more than one device at a time.I have assumed that it is some automated or virtual client as I'm pretty certain my network has not been breached. I have a 9 character password with a relatively random alphanumeric combination, although I haven't tried changing the password (I live in a share house with with a bunch of devices using wireless, so I haven't yet bothered). What I don't understand is how it has connected with the xx.xx.169.xx range at all. I have a Belkin 'Share' Wireless N Modem Router and at some stage there was a 'guest' network but that has since been disabled and I still am seeing the extra address. I have attached a screen shot of the DHCP client list on the router.The following is a list of devices that may be on the network at times, I'm thinking one of these may be responsible for the problem:
Windows Vista Desktop - Only LAN device
PS3
Macbook
Epson wireless printer
Android HTC Desire Mobile Phone
Laptops running various Windows versions (XP, Vista and 7)
A few thoughts I had:
- the android phone is capable of running a wireless hotspot, may have to look into it to see if if has been operating as an access point into the Belkin router, but assumed this wouldn't bring up clients connected to the phone on the home router.
- The desktop has PS3 Media server installed to stream video to the PS3 over the network (not that I have ever managed to get it to work), however this is not ever open on the desktop.
Do the problem caused by the modems itself or it just sign of faulty Ethernet switch (using 20 port Allied Telesis ethernet switch). Sometimes I cannot connect to internet due to "unidentified network" buy i can resolve this problem by restarting my modem + switch.
I have purchased E2500 and i am having following problems:
1. DHCP client list not showing - only shows when i reboot the router. After some time, the list never shows even when i press refresh button 2. I can only reserve IP when i reboot the router - after some time i cannot do this action also
I have upgraded to latest firmware and also peformed reset as directed by support.
I could get a list of clients on the E3200 wireless (or wired) ports. I have my E3200 setup as a WAP LAN-LAN off a switch and it is not the DHCP server on the network. I can see a list of MACs on the client list, but no client names and no IP addresses. They are definitely named and show up on the WRT54GL (DHCP and NAT) as devices
I just started having this problem yesterday. I was experiencing weird downloading/internet browsing issues and couldn't figure out what the problem was. I started looking around my router settings and noticed that in my DHCP Client list, my computer isn't in it. The router is hooked up to the computer, so it's not wireless. My phone and my girlfriend's laptop are listed, but the main computer isn't. It's especially causing problems with port forwarding. Downloads will stop because the port isn't showing as open. I'm running 64 bit Windows 7 and a Belkin N+ Wireless Router, model F5D8235-4.Firmware is up to date.
Region : France Model : TD-W8968 Hardware Version : V1 Firmware Version : TD-W8968_V1_120926 ISP : SFR Device in question: siemans C610 IP voip phone Configuration:
* The C610 is directly connected to TD W8968 via the ethernet port number 3 >> ethernet port number 1 is connected to the devolo homeplug 200AVPLUS . The PC is at the other end of the homeplug network
* The DHCP address starts at 192.168.1.100 - 192.168.1.199.
Symptom:
1. It takes a long time (about 2-3 minutes) for the C610IP to obtain the IP address of 192.168.1.100 after the synchronisation of the ADSL line is finished 2. In the DHCP client list, I could only see the IP address of the PC (192.168.1.101) but not the C610 IP. However, if I type 192.168.1.100, I could access to the configuration page of the C610 IP. - I only managed to see the C610IP once in the DHCP client list.
I tried to unplug -> replug the router but to no avail.
I have a Wireless N router model F5D8236-4 v2 (01) with firmware 2.00.04 (Nov 12 2008 10:51:08) and it's not showing all issued wireless or Wired IP addresses in DHCP Client List.
They all have IP addresses and connect to the internet through the router, but in the router administration page, they're not listing. The Windows devices all show but most of the Mac devices are not, nor is my XBox 360.
My reason for investigating this is because the router seems to keep losing the Mac devices and a router reboot fixes it, but it shouldn't have this problem because all the Windows devices just seem to work.
According to the support page I have the latest available (dated November 12, 2008 which really seems kinda old to me for a Wireless N router). Are there any plans for a new firmware offering for this modem or have you already deprecated it as "legacy equipment"?

So I've been checking my router DHCP list and I usually use the WPS feature to add devices. I know how many devices I have and which ones are wireless etc. I've made address reservations on all the devices that I have and know of. One feature that really frustrates me (which is missing) is no way to rename a device. My iPhone is named: Reggie's iPhone yet the 4300 picks it up as Unknown... I dont understand why. I've renamed it on the iPhone to different things and restarted it but still it comes up as that. I have 2 Nexus 7s and both come up with wierd names, one is for my wife and one is for me and I wish there was a way to name it proper.
Question is: Will the name edit feature ever get added to it? I dont get why it's not there now, it's not really something major (I have a 5 year old router that even has that... and it cant even support N). It's really frustrating to have to guess and check the devices on my network because most of them come up as unknowns.
Right now I'm trying to located another device that's coming up as unknown and now matter how much I try, since the router lacks any feature to assist finding it, it's really frustrating.
something else i noticed: my DHCP List shows all the devices connected with their IP addresses, yet I went into CMD and was doing a random ping command. I'm able to ping 192.168.0.114 with perfect stats back yet on my DHCP List it shows the highest IP is at 192.168.0.112.... Is something wrong here? Is it supposed to not pick up the IPs it gives out? And of course since there isnt a way to tell if that IP is for a WIFI or ethernet device, I have no idea what that device is...
yet i found another ip address on my network by using the ping command. actually I went ahead and did arp -a to find out all the ips with mac addresses. this is a serious flaw with the security of this router!!
I have a few desktops in my home network with a new E4200 router. Have to add my wifes Lenovo notebook to the net and activated MAC filtering as addition to the WPA2.Set her MAC address in the filter list. Only one MAC is allowed to access WLAN.An hour later I see in the Filter list four (4) different and unknown MAC adresses added to the list.
I have a setup using LogMeIn Hamachi and the network type creates a Windows Bridge. I also use the DHCP Reservations List to assign the same IP to specific devices. Well I have the MAC Address for my NIC in the list which works when I am not using the bridge. When using the bridge, of course the MAC address changes and when I try to add it to the list I get the following message in a popup window. The MAC Address is 02:e0:61:05:45:3e I have tried manually entering it, letting the router enter it from the list of computers and just to rule out something stupid, I have tried changing the letters to upper case and removing the colons.
Another issue I can see when this issue is resolved is that I do not believe it will let me add this reservation since I will be using the same IP used by another reservation. My DGL-4500 allowed this if I had the other reservations using the same IP disabled.Below these comments/rants are some feature requests. I have put them last as some of the requests are explained in the comment/rant section.I have read through this list and I have to say that after I purchased the router, which I ordered on-line, I was dreading it, but I have not had issues. It is possible that I am not using features that cause this issue. I believe the issues occur when using certain configurations with the "Enable Advanced DNS Service" enabled. I am not using this service. Since I knew people were having issue s with it, I wanted to see my results leaving that out. I have had this router running since a week before Christmas and I have many Virtual Server entires, QoS and port forwarding entries, https based remote administration, both 5GHz and 2.4GHz networks enabled supporting a/b/g/n(on both networks) and a guest network enabled on both bands all supporting WPA (TKIP and AES). I have 2 Giga wired connections that are always active, a 100Mb connection that is on an off but used almost daily, 2 Laptops that use the 2.4GHz network daily and one is 802.11g 54Mb and the other is 802.11n 150Mb and they are on at the same time almost daily, a printer that is on and used multiple times a week that uses 802.11g and a game system that uses 802.11a this device is used daily. Most devices are on and used at the same time daily and we have a good deal of regular Internet traffic and moderate other network traffic during these times. At night all computers are backed up over the network and most of the other network devices are off or not during this time. Other than having to reboot my Internet hardware provided by my ISP, I have not had issues. The router has been rebooted for config changes and I usually cycle it when I cycle the Internet hardware. Point is, so far no issues, good performance and it works and I have of course had other devices connected using the guest network and I have been testing features, performance, etc.
What's up with having so much variation in how features work across routers?e.g. My DHCP Reservation issue above. This router does not work with a setup like my DGL-4500.This router allows a preset amount of services like QoS and Virtual Server entries while the DGL-4500 just lets you add entries. Now maybe there is a limit and it just looks like there is no limit. Of course, there is at least a limit that is reached when you have used a certain amount of memory with the configuration.so many routers while leaving gaps and the lack of feature explanation and comparison?I switched to this router because I wanted a dual band setup which my DGL-4500 does not provide. That leads to the issue of the new way D-Link deals with dual-band. When I purchased the router it did not list that you had to choose 2.4GHz or 5GHz or it is not simultaneous dual-band. I was duped because I used to install DWL-7100AP for people that needed better wireless options for home businesses and small businesses and that provides simultaneous dual-band and back then if it was dual-band it was simultaneous. But I am disappointed in some of the features lost like WISH support and a few options here and there which do not seem like they are specific to gaming routers and this router is more on the mid range and low high range end of consumer, prosumer, home business and lower traffic small business routers, so why is it missing these features and why does it have the limitations I listed in the "variation in how features work" section above?
Other examples of lack of feature clarity are with Game Fuel, HD FUEL and Intelligent QoS. Isn't Game Fuel Intelligent QoS of some sort. Now from the example provided in the overview for the DGL-4500, Game Fuel optimizes game performance, but it does not say this is automatic or if it works along with the rules you set in the Game Fuel section which is the same as the QoS Engine section in the DIR-825. The difference is that the DIR-825 has a "Enable QoS Engine" option while the DGL-4500 has an "Enable Game Fuel" option. It seems that Intelligent QoS does what Game Fuel does, but expands that to VOIP, Media Streaming, etc. and it may be more automatic. HD Fuel in the only place I have seen it mentioned seems to refer to the combination of Intelligent QoS and the inclusion of 5GHz wireless support. Of course there is no version and feature documentation and in fact while the overview of the DIR-825 talks about gaming with Intelligent QoS, but if you bring up a comparison of routers, the chart has no in the gaming section for the DIR-825. I can't say I have noticed better or worse gaming performance with the DIR-825 compared with the DGL-4500, but given the shear lack of documentation on how to use Game Fuel and Intelligent QoS properly, who knows if I have this setup correctly. I will say the QoS Engine section in the DIR-825 is easier to use than the Game Fuel section in the DGL-4500.
1) The ability to reduce the brightness of the status lights, set them to solid if enabled with brightness options and to set them to off with an option to have some very faint light to show that the router is on. Of course I should be able to set different options to be applied at specific times.
2) Add the applicable features missing from the DIR-825 that are found in the DGL-4500 and applicable features from other routers. Also, get them all so they work the same on each router and let get the best from them all and make that the standard. e.g. In my DHCP reservation example above don't set the standard to the limitations of the DIR-825, but make the DGL-4500 function set or better function set of all routers combined for each feature the standard with-in router categories. e.g. the DIR-825, DGL-4500 and DIR-855 would be in the high end router category for consumer, prosumer, home business and lower traffic small business routers.
3) For DHCP reservations, you should not be limited to the DHCP IP Address Range.
4) On the log-in screen, get a better captcha and fix the tab order.
5) Add a log-out option in the web interface.
6) Allow for a next hop option in the DCHP server section. It would be cool, if there could be a list of IPs allows one to be enabled at a time.
7) Allow different DHCP server settings for each network. There are 5 on the DIR-825. Wired, 2.4GHz regular, 2.4GHz Guest, 5GHz regular and 5GHz Guest. Would be nice if you could set a couple of VLANs on the Ethernet ports and then have different DHCP setings for each VLAN.
For guest wireless networks, allow rules to be set to allow access to certain services on the network. E.g. I may want to allow printing. So allow a single port or multiple ports with easy settings for consecutive port ranges to be opened to an IP, IP range or all IPs and allow all ports for an IP or range of IPs. Of course, leave the allow full access option.
8a) Allow users to set rule sets that can be enabled/disabled like the full access option.
8b) Allow a control that can be set in the rule sets that controls if the wireless devices can talk to each other and another that controls if they can access devices on the wired network and another that controls if the wireless devices can access the Internet.
8c) Allow rules above to be limited to be applied to specific MAC Addresses.
8d) These options would be good to have for the non-guest wireless networks and wired network as well.
A small network and uses the Linksys Router BEFSR81 as dhcp.the default Number of addresses is 50 and starts 10.0.0.100 to 10.0.0.149.A new Cisco IP Phone just introduced requires ip addresses and have noticed running out of addreses.Can I increase the number to 120 so that the address range would start from 10.0.0.100 to 10.0.0.219, also, I have a VPN device which automatically configures itself for 10.0.0.199 address and this is /24 network configuration.
Using Android phone and have to set up Port Forwarding to access the cameras. I have to change the IP Address to a static one instead of the one issued by the Router. How do I change the IP Address of the camera to one outside the DHCP range?
we have a 3560 switch configured with EIGRP with dhcp. We have a user that we cannot ping, however the interface show up / up and no errors on interface. the ip address is 10.2.0.199 - however we have dhcp configured to exclude the range from dhcp ip dhcp excluded-address 10.22.0.1 10.22.0.200 how can this work station get a dhcp address if we have that ip range excluded from the dhcp pool?
The user is off a different switch that is a uplink to this distribution switch. Traceroutes shows that the problem is with the distribution switch.
I have DHCP server running in windows 2003. Presently its unable to provide Ip address for VPN clients who connect remotely. What I should do / reconfigure in DHCP, so that the DHCP server provides address for VPN clients.
Currently we're providing DHCP to wireless clients from a dhcp pool on a cisco 6500. Due to new requirements we need to move to windows 2008 dhcp and when I test this on an unused WLC (7.0.235.0) the client doesn't get an address.
When I do a packet capture on the client I see it requesting dhcp but not getting any response from the server. When I do a dhcp debug on the client I see the same (see attached file).
This seems to me to be a server issue but the same server is supplying addresses to wired clients.
I have the WRT400N router with the latest firmware. Recently I have noticed a device in my DHCP that I do not recognize. It is not device I own (believe me, I have racked my brain and confirmed) as it shows as an Acer pc. I cannot ping the IP address however. I have rebooted my router several times thinking maybe it's a former connected device but saved in memory but it keeps coming back. I am thinking possibly it is someone hi-jacking my Internet, but not sure. I am using WEP security but it shows a LAN connection which is strange for a wireless device. The only hard wired pc is my HP.
DHCP enabled with default settings. Dynamic IP range from 192.168.0.100 - 192.168.0.199.Router shows laptop with 192.168.0.199 however when I check the IP on laptop I have 192.168.100.10 and both laptops are connected on my SSID with 90% signal strenght.
The wireless client can't get the DHCP address when I enable the On-MAC-Filter-failure, MAC Filtering and Web Auth. Client can get the DHCP address when I only enable the Web Auth in the same WLAN SSID. The WiSM verion is v7.0.235.0. [code]
have an unknown mac address listed in my router's connected devices pane. There is no ip address or device name listed. I know the mac addresses of the machines I have put on the internet, and i don't recognize that one. Router: Netgear N300 WNR2000v
I have 2 units Cisco WLC 5508 running software version 7.0.220 with 70 over units Cisco AP 1262N and 1242AG. Some of wireless clients having problem to get the correct IP address from the DHCP server. There are 2 units of Microsoft DHCP. Both DHCP server ip have been configured on the Interface at the WLC. The core switch also being configured with ip helper. I've attached the debug output of one of the wireless client during the problem.
I've got a WRT54G v6 that is password protected via WPA2 Personal TKIP+AES, and SSID broadcast enabled. In the Status menu > Local Netork > DHCP Clients Table there is a MAC Address listed that none of my devices have.
We are running Cisco Wireless Control Sytem (v7.0.164.0) with 4 - WLCs (v5.2.193.0) and about a 100 Aironets and I was wondering how to get WCS to identify the Client usernames? When trying to view monitored clients usernames, all it shows is Client Username <unknown>, though their MAC and IPs are correct. I'm not sure if this has to do with mobility anchors or not, but currently we have none setup in case. How to resolve the machine name or actual username that is logged in... either one.
When I go into the Network Settings, and the end of the page I find a list named "Number of Dynamic DHCP clients: 7". As far as I know, I should only see 4, all 4 laptops; however, I see 2 UNKNOWN entries in this list, and one name "Macondo". Each of these entries have an option (a link) saying "Revoke" and other "Reserve". I am just wonder if these entries are intruders in my home network. What should I do? I am afraid to break my internet connection. By the way, I set up every single one of my family 4 laptops at home with a WPA-PSK using a very long key.
I picked up an E1200 and set it up successfully. I am using wireless MAC filtering, and decided to pull up the list of connected wireless clients (Wireless >> Wireless MAC Filter >> push "Wireless Client List" button).Immediately after this the Web UI of the E1200 becomes inaccessible. It still routes traffic, and the router remains pingable, but it will not allow access to the Web UI for several minutes. The error that appears upon attempt to access the Web UI during this time window is similar to the above, but reads "Error 102 (net::ERR_CONNECTION_REFUSED): The server refused the connection."
I have tried this in Google Chrome, Firefox 4, and MSIE on two separate computers. Each browser displays the error a bit differently (MSIE, for example, just says it can't display the page and gives no further detail) but the net results are always the same. I have tried resetting the device to factory defaults in addition to re-downloading the firmware from the Cisco/Linksys website and installing it. No improvement.
I have also noted that the Log (Administration >> Log; and yes, I have it enabled) doesn't appear to be picking up anything at all. In fact, the Security log, which supposedly (according to the Help) "displays the login information for the Router’s browser-based utility," is also blank.
I have the WRT160N router for 3.5 yrs and it's worked perfectly since installing it. About two weeks ago it began intermittently dropping cable connection. First few times I thought I could resolve it by unplugging/plugging router & modem so they can "re-syn" to the cable connection. That still works but now it occurs sometimes multiple times within a few minutes/hours and then won't happen again for an entire day/days. The other day I had connectivity but instead of the usual 5 bars I only had 3 while using my laptop in the same spot in the house as usual.
I've got an E4200v1 running 1.0.04 firmware with guest access enabled. I'd like to find out who is logged in using the guest access. Is there a way to get a list of the DHCP clients on the guest network? I'm able to do this for the non-guest access via the WEB interface's Status->Local Network->DHCP Clients Table page. But I can't find a similar table for the guest network.
I have an e4200 set up and working on fios as a pppoe router properly with a dozen devices connected to it via dhcp. The dhcp range i configured in the e4200 is 192.168.1 100 to start with, and a mask of 255.255.255.0.
All the dhcp devices connected to the router start with 192.168.1.1xx. My Dell Inspirion with Windows 7 has an ipv4 address of 192.168.15.2. I cannot figure out how it gets this address, even after I release and renew the address on the Dell.
Everything is working fine so I guess there is something I just do not understand.
We had a new linux server installed at a remote office yesterday, unfortunately the guy installing the server forgot to change the IP addresses, doh. It's plugged into a C877 and I can see the port is up/up and I see the mac address using 'sh mac-address-table'. The ip address on the server is unknown but it's unlikely to be in the correct subnet for the vlan it's attached to.
Is there a way I can add an arp entry manually to the router, then ssh to the server and correct the ip address? Or is there some other way to establish the IP address of the server? It's gonna be a pain to revisit the office and there's no one there that can get into the server room to do anything from the console.
how can I show the DHCP-range of a router if I don't have privilege level? (not in enable-mode),I can do a "show ip dhcp pool" - this will show me the range which is configured with the network-command.But there are also some dhcp-exclude-addresses which I can't see.... (I did a test on a router with full privilege-access)I need this because I have a router with limited access from our provider.
how I can get to the DHCP client table on a Cisco 891 Router ? We just upgraded our router from a WRVS4400N to the Cisco 891. THe WRVS4400N has the feature DHCP client table that I can see the Client host Name and IP address,Mac Address I have CCP and CCP express installed on my system?
I have a XSR-1805 (Version 7.5.0.0) enterasys router here. Got SNMP server to work successfully. The thing is that I couldn't make the router restrict a range of address allowed to use a community. Only 10.1.0.13 is allowed to use SNMP in this case.
