Answer 2

Answer:

0.0.0.0 is the host address

Explanation:

When there is no specific route or no specific network ID then the default route is used. This is used when all the other route fails too. The network id is 0.0.0.0 and the network mask will be "0.0.0.0."

255.255.255.255 is the host route which allows the packet to be sent to the particular IP address. Network mask will be 255.255.255.255.

"127.0.0.1" is the "local host" or loop back address.
