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