Computer Not Using Correct IP Address
Sep 25, 2012
I am currently living in student halls, and so far I have been successfully using the halls' provided internet (ethernet port in wall) via a wireless router (belkin wireless ADSL). Until now.I have been unable to connect or the internet either via the router, or by direct connection to the wall.Whilst connected directly into the wall socket via the ethernet cable, my pc still thinks that I am connecting directly into the modem, and still labels the wired LAN connection as 'belkin 54g', despite the router not being connected at all.I have called the technical support for the network, and they have told me that my computer is assigning the wrong ipv4 address, and they had me do a cmd prompt and run ipconfig /reset and ipconfig /renew. This still did not solve the problem, as my PC still tried to connect with the same incorrect IP address. I know the problem is not with the ethernet port or cable, as I have tried in another room that has a working connection, and I still am unable to connect to the internet (DNS error on chrome).

I am trying to assign a static IP address for network adaptor as i am going to be using it to install Active Directory on VMWare Worksation. I was told that if i went into Device Manager within my worksation then Advance > Locall Administered Address and set a static IP, when i install AD and it asks to whether set a static or dynamic IP it would continue the install process. However, after setting a static ip it did not, can somebody tell me how i can set the correct IP address for me to continue instaling AD.

Given an IP address range, select the correct subnet mask for the scenario. IP address: 132.250.0.0/16, You need to create 100 networks with a minimum of 500 hosts per network. What is the correct Subnet mask and the 10th subnet address range?

I have two sites.Main site (local) has two Vlans: Vlan1 and Vlan2. Each has its own IP address range.VLAN 1 is the default Vlan and is used for CORPorate traffic. IP range 10.33.4.*VLAN 2 is for guest access to the internet IP range 10.10.10.*I have a WLC4402 on the this site with 2 WLANs: CORP on Vlan1 and GUEST on Vlan2.
Branch site (remote) which has 2 Vlans: Vlan1 and Vlan2. Each has its own IP address range.VLAN 1 is the default Vlan and is used for CORPorate traffic. IP range 10.125.15.*VLAN 2 is for guest access to the internet IP range 10.10.11.*I have an 1141 on this site using HREAP.
Locally, if you connect to CORP, you get a CORP ip address and access to CORP network. If you connect to GUEST, you get a guest ip address and guest access to the guest network. Simple so far....
Remotely, if you connect to CORP, you get a CORP ip address 10.125.15.x and access to CORP network (great). If you connect to GUEST, you get a CORP ip address 10.125.15.x and access to CORP network (not great). This is with the HREAP native vlan ID for the access point set to 2 on the controller.If I set the native vlan ID to 1 on the controller, I can not get an IP address at all.If I do not set the native vlan ID on the controller, I can not get an IP address at all.

Just inserted a new 5508 WLC into the network. We current have 3 4404 WLCs, and there was a need to duplicate, as much as possible, the configurations on the 4404s, and the design. The 5508 came online as expected. We moved a few access points over to it. The APs got the correct address range. The clients are expected to get addresses in the same scope range as the APs. However, the clients are receiving addresses in the management IP scope.I know there are two "not a good way to do it" in here. Why is the management address range in the DHCP scope, and why are the clients using the same scope as the APs. We are going to change that. For now, the AP and client in the same range has been going on since we rolled out wireless in 2006.The 8 ports on the 5508 are configured for LAG. There is no dedicated port for management. They tell me not to do that on a 5508.

We have an ADSL connection and use a D-Link DSL-320B modem. We have a D-Link DIR-120 router connected to this modem. This has worked perfectly fine up until today when we disconnected the router and connected a computer (call it A) directly to the modem because it was getting an unusable connection through the router for some reason. We later also performed a factory reset on the DIR-120 router.
Unfortunately, after the above steps the router did not receive any IP address (through DHCP) from the ADSL connection anymore. During my attempts to debug this I noticed that my laptop (call it B) didn't get any IP address either (when connected directly to the modem). I noticed the following syslog entries repeating over and over while trying to connect: [code]
At this point computer A could still get a connection just fine tho (when connected directly to the modem).
I then tried to change the MAC address of the router to an arbitrary one (a copy of computer B's MAC address but with the last digit increased by one). The router still did not get assigned any IP address. Finally I tried making the router clone the MAC address of a third computer (call it C). C has never been connected directly to the modem. Doing this worked. After cloning the MAC address of computer C the router is immediately assigned an IP address and the internet connection works as it did prior to all this.
Now, my question is, why would computer B and the original MAC address of the router not be able to get an IP address while two other computers worked just fine? Why would changing to an arbitrary MAC address not work while cloning the MAC address of another computer did? Could the router's MAC address have been blocked by the ISP for some reason (and what could cause this)?
but my situation seems more like a blacklisting of some MAC addresses rather then allowing just a single MAC address.

when i was on the computer last night, i noticed someone else's address at the upper right hand corner nest to "sign in". The person's address was Jaydogwalker45@yahoo.com. I also noticed a green circle next to the address, so i clicked it and i had the option of signing him out, so i did.

I started my PC (aser) as usuao but did not connect to internet that i am using TP Link modem/router, I turned laptop on and get conected the wireless is working fine, serached about TP links solutions and applied all of them, before I was using "obtain IP automatically" then I used to insert the required IPs manually, applied and save and restarted several times... still cannot connect to the internet while I still connected to the same modem+router via laptop wireless connection,
Finally I decided to format and installed new OS XP, though some wrong error was with my OS, unfortunately even after installing new OS still not able to connect, I checked the IP and tried both options and still cant access, i never experienced such..

I have 2 servers. 1 is a terminal server windows 2003 sb terminal server.(working fine) and the other is server 2003 small business DC configured with dhcp, dns, SQL, & wins. Last week one of the network programs that is located on the DC started refusing connections.So doing some trouble shooting I noticed that when I ping the server name I get a local address of *.*.*.42 when the address the machine is assigned is *.*.*.5. When I do an Ipconfig /all on the DC it only shows the *.*.*.5 number. I look in DHCP and *.*.*.5 is reserved for the DC Computer. And the *.*.*.42 isn't even in the address leases. I have also looked through the DNS settings and see no alias with the .42 number. And the number does not show up in the reverse lookup zone either.

Have a computer running windows xp. Whenever I plug in my internet cable it says 'Acquiring Network Address'. I have left it for over and hour but it still says the same thing. I have connected other computers to the router with the same cable and they work perfectly. I have also tried channging the linkspeed for the network connection, renewing my ip address, repairing the network connection and disabling and enabling the connection.

There are 6 computers in our home network. It happens every few months or so that router would not assign valid IP address to one of the computers. So, most of the time everything works well, but there comes a moment when one of the computers (but not others) can't get valid IP address.We try turning off and then on the router and it solves the problem most of the time. But, there are cases when turning off and on the router won't solve the problem.

When I was hosting a server on minecraft, a few people complained that the server was down. It was, and the problem is that my router switched to a dynamic IP after comcast installed a security system to my house. If I try to reset the router, the system goes down and takes a helluva long time to get back up. Whenever I try to switch to a static IP, however, I lose internet connection. Wondering how to fix this. Or do I have to switch back to my laptop - which might also not even work. (I'll go try that, but I'm using my desktop because it has extra RAM.)

I have an HP 510 laptop running windows xp. Wherever i go, i am able to connect through wifi with a password except for where i live. I have had no problems connecting anywhere else. All other laptops and pc's connect through the network i cant access. I get a 'limited or no connectivity' message with details displaying either 'network did not assign a network address to the computer', 'cannot connect to the internet' or 'cannot renew ip address. I reviewed a few older posts and have tried ipconfig/release, ipconfig/renew, ipconfig/all to no avail. i also tried netsh ip reset reset.log and netsh windows catalog(or something along those lines) from the earlier post i read, still nothing. I do notice that when i go to properties the wep password always reverts to one i did not enter, and once in a great while when i re-enter it the icon will show 'connected to network, excellent signal strength' but Internet Explorer says not able to connect. I cant seem to figure out why i connect fine everywhere else, and why every other 'guest' computer connects to this network.
i connect using Intel(R) PRO/wireless 2200BG under properties>general under properties>wireless networks>association use windows to config is checked under properties>network>properties the network authentication is 'open' and data encryption is set to 'wep' while the network key reverts to something i did not enter. key provided is not checked under properties>wireless networks>authentication 'enable ieee 802.1x authentication for this network is not checked

I have two servers running behind my D-Link DIR-655 NAT router. Obviously, I cannot allow outside access to both of them simultaneously without putting them on different external ports, which I don't want to do. (DNS can only redirect to the common external IP of my router, not the unique internal IPs of my servers.) The easiest solution I can think of to this is simply to put one of the servers completely outside of the router so that it grabs its own IP address from Comcast (and thus allows me to change my DNS records so that the destination IPs are different.) Is this possible, and if it is, how do I do it?
P.S. I've already tried putting one server into the DMZ (Demilitarized Zone) on my router to no avail.

RARP (Reverse Address Resolution Protocol) is a protocol by which a physical machine in a local area network can request to learn its IP address from a gateway server's Address Resolution Protocol (ARP) table or cache. A network administrator creates a table in a local area network's gateway router that maps the physical machine (or Media Access Control - MAC address) addresses to corresponding Internet Protocol addresses.When a new machine is set up, its RARP client program requests from the RARP server on the router to be sent its IP address. Assuming that an entry has been set up in the router table, the RARP server will return the IP address to the machine which can store it for future use.Among the passage of words i read, there was this sentence i were not sure, "A network administrator creates a table in a local area network's gateway router that maps the physical machine (or Media Access Control - MAC address) addresses to corresponding Internet Protocol addresses." Does it means each time a host computer joins in the ethernet LAN, the network administrator would manually add in it's MAC address in the router table, so it would allow the newly joined computer to request IP address from it's MAC address?
