Hello I am new to your site, I like it so far. I actually want to see if I have answered two questions on my final exam at school correctly.
1) A router connects two networks: 126.96.36.199 and 188.8.131.52. The router is assigned the first IP address for each network and uses the standard class mask. A host has the IP address of 184.108.40.206. What default gateway will be assigned to this host?
Is the answer to # 1 - 220.127.116.11 ?
2) What is the network number for IP address 18.104.22.168 if the standard mask is used?
Is the answer to # 2 - 255.255.0.0 ?

1. The default gateway cannot be a network address, or a broadcast address. If you have assigned the 22.214.171.124 and 126.96.36.199 to the appropriate interfaces, then the the node 188.8.131.52 sits on the 184.108.40.206 network. The first host address on the network has been assigned to the router interface, and it is that address (220.127.116.11) on the router interface that is the default gateway.
Likewise, any node on the 18.104.22.168 network is going to have 22.214.171.124 as it's default gateway.
2. Assuming a standard 16 bit class B mask, the network address for 126.96.36.199 would be 188.8.131.52.
