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: 220.127.116.11 and 18.104.22.168. The router is assigned the first IP address for each network and uses the standard class mask. A host has the IP address of 22.214.171.124. What default gateway will be assigned to this host?
Is the answer to # 1 - 126.96.36.199 ?
2) What is the network number for IP address 188.8.131.52 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 184.108.40.206 and 220.127.116.11 to the appropriate interfaces, then the the node 18.104.22.168 sits on the 22.214.171.124 network. The first host address on the network has been assigned to the router interface, and it is that address (126.96.36.199) on the router interface that is the default gateway.
Likewise, any node on the 188.8.131.52 network is going to have 184.108.40.206 as it's default gateway.
2. Assuming a standard 16 bit class B mask, the network address for 220.127.116.11 would be 18.104.22.168.
