I want to calculate Subnet Mask for 3 Router Each one in separate building the First building need 60 host and the second building 25 host and the last one 25 host .
Knowing that the company currently reserved public class C network address 210.2.1.0/24 for internal address and subnet 210.15.10.0/30 for the connection to the Internet router.
I am using TP-Link wireless router model no. TL-WR941ND.my isp provided static ip via cable modem.ip = a.b.c.d subnet = 255.255.255.254 = /31 but the router does not support subnet mask saying wrong subnet mask?

View 4 Replies View RelatedI have old interface hardware with Static IP 10.2.2.200 and on the same switch I have computers with IPs of 10.4.1.0 If I change subnet to 255.0.0.0 old hardware with 10.2.2.200 will be accessible. The problem is that I would like to have 255.255.255.0 as subnet but it should still be possible to access 10.2.2.200. Can I add Static route for oldhardware in XP without adding gateway settings? The most simple would be to put all on same subnet but it is not possible due to a various reasons. The computers are running Windows XP

View 1 Replies View RelatedWe have an ASA 5520, working fine.One of the interfaces is connected to users PCs and printers mainly. Last months the number of devices has grown rapidly, and we would like to make some changes in it in order for it to be able to host new devices.We thought on change subnet mask of actual subnet (10.0.2.0/24) to 10.0.2.0/23, so it can hold as many devices.I understand I have to make some changes in the ASA, but my question is:What will happend to the acces rules I have created?Will I need to create them again? There are some objects which carry information about subnet mask, so I suppose I will need to redefine them, but for those without any subnet mask information, will I have to redefine them?
View 2 Replies View Relatedafter recovering from the PPPoE-port-forwarding-fiasco I had with the RV180 (url...), I decided to try again with a Small Business Router from Cisco. This time I took the RV042G, hoping that the higher age of this product comes with a more mature firmware.So far the functions I need, work satisfying. There is only one issue: The subnet-mask is only configurable using a dropdown-menu. I've read the posts from the Cisco-Support staff saying, that this is because it is only a SMB Router. So, we are a small business and we use the 172.20.x.y net for several reasons. One of it is to distinguish and group several network devices using the third block of the IP. Eg. our printers IPs start with 172.20.5.x and so on.
My question is: Is it really impossible to change the subnet-mask dropdown-menu to a simple text-field in the frontend? Because it is possible to change the subnet to whatever one needs by a little cURL-magic: [code] This sets the new subnet-mask permanently (even survives a reboot and is displayed correctly on the system-status page) and I have not discovered any problems.The only thing is, if you change settings on the setup -> network page, the netmask is reset and you have to rerun this script.
We have 10 ADSL lines and 5 of them goes in the load balancer (One gateway) and the rests are used as default gateways for internet access. We use ADSL routers as access points for internet, but those routers should be part of our network and should be given an address in order for them to act as default gateways for internet access. I'm facing a real prob with the ADSL routers Linksys WAG54G2 because they doesn't support a subnet mask 255.255.0.0 Any recommendation for an ADSL router model that support a netmask 255.255.0.0 ?

View 1 Replies View RelatedAn IP packet of size 1500 bytes passes through two network segments before it reaches its destination. The header size of this packet is 20 bytes. The maximum size of an IP packet in the first intermediate network (its MTU) is 1024 bytes, and that in the second network is 576 bytes.Explain how the IP packet described above would be fragmented into smaller parts in a router, paying particular attention to the flag bits and to the fragment offset field in the header.
- Fragmentation and reassembly needs to break a data-gram into an almost random number of pieces that later can reassembled.
- It uses the identification field to ensure that fragments of different datagrams are not mixed.
- IP packet of 1500 bytes comprises 1480 bytes of data and a 20-byte header.
- In the first intermediate network, the packet size of 1024 bytes allows for 1000 bytes of data plus a 20-byte IP
header.[code]

View 1 Replies View RelatedGiven the IP address of 172.16.10.22 and the network mask of 255.255.255.240... answer the following:
What is the network address?
What is the broadcast address?
What is the valid host IP range?
What I have done so far:
Part 1 - Broadcast address
172.16.10.22 - 10101100.00010000.00001010.00010110
255.255.255.240 - 11111111.11111111.11111111.11110000
Researching different ways to find the Broadcast address I took the binary IP address and replaced all numbers with 1's for the host bits identified in the subnet mask and came up with:
172.16.10.31 - 10101100.00010000.00001010.00011111
Is that the correct Broadcast address?
Part 2 - Network address
I am not sure what is meant by the network address and all my research has come up with either MAC addresses (obviously wrong) or CIDR notation...How do I calculate the network address?
Part 3 - List of valid IP's
Using the same address 172.16.10.22/28 I did the following:
28 is closest to 32 (block wise) so 32 - 28 = 4... 2 ^ 4 = 16 (block size)
IP address listing:
172.16.0.0
172.16.16.0
172.16.32.0
172.16.48.0
172.16.64.0
and so on...
The IP address in question is 172.16.10.22 and falls in the 172.16.0.0 - 172.16.15.0 block...
Is this the correct list of valid IPs?
I need to know exactly how much bandwidth my service provider is giving me throught an MPLS network. My providers tells me that I am capped at 5 mbps with 4 T1 circuits but I believe that I am receiving 6 mbps.
I have a remote site in Dallas with a 2850 and another site as a head end in Michiagan which is a 7206 router.
What exactly can I do during non-business to test to see what the bandwidth is between the 2 locations? Is there some type of command that I can run on the router to test this?
I want to measure the the ospf convergence time on the given network topology (assume 5 nodes - partial mesh topology).I am using quagga software as routing software on linux box. Quagga is runnign fine and network is converged, able to see all the routes.. Quagga software is logging all the osfp information includign packets,state machines,etc.I am going to disconnect a link between node a to node b. and i want to measure the convergence time of the network.What is the network convergence time?My answer is, The time taken to reflect the topology change (link down/up, network condition change) to all the routers on the topology.Some routers(close by routers to the topology change) will get converged fast, and some routers(far away from the topology change) will have the higher convergence time. we have to take the highest convergence time of the router on the topology and we can says thats the ospf network convergence time.

The ultimate setup thread mentioned only connecting routers together, and it would be cheaper (would it?) to get a new router and a switch instead of two routers of the same type.I admit I don't know much about networking. I tried Googling, but kept getting results about people asking what the difference between a switch and a router is, or how to set up two subnets on one router or switch.My current router is pretty old, its a V2 WRT54GS. I don't want to let it go but the lack of WiFi-n and Gigabit can get limiting, especially when sending large files across systems on a network or streaming video.However, I have another issue that wouldn't really be resolved by replacing it anyway, the fact that most if not all home routers have 4 Ethernet ports max. The amount of wired devices I use in the same area is increasing, and while I can switch some of them to wireless to make room for the wired-only ones, I would prefer not to. Some of these are multimedia or gaming devices and I would prefer the lower latency as well as higher LAN network speeds of Ethernet for them. I was told that I can connect a switch to my router and have everything act as if its on the same subnet.Will devices plugged directly into the router and those on the switch act as if they are on the same subnet and see each other without issue? Wouldn't this cut down on the speed of the devices if I have several plugged into the switch since they are sharing the single port the switch is plugged into the router with? Would it be better to get a switch with several gigabit ports and just plug everything into that for LAN speed? Its not like the WAN connection will come anywhere even close to 100Mbit, much less Gigabit, but would that still cause a bottleneck if several devices are trying to access the WAN over a switch that is plugged into a single port on the router, or no? Or would it be better to plug as many devices as I can into the router and the rest into the switch?
P.S. I use static IPs because I like to know which device has what IP to communicate with them directly if need be, and the WRT54GS has no way for my to reserve an IP based on port, MAC, or anything. Would that cause a problem? Is there any way to assign/reserve IPs on the newer routers (especially Linksys) with their stock firmware so I can switch to DHCP for guest devices?
