Question

Larke is trying to come up with a subnet mask so that three servers with the IP addresses 172.16.31.10, 172.16.30.15, and 172.16.31.206 are in the same network. Which of the following subnet masks will accommodate this requirement?

a. 255.255.255.0
b. 255.255.255.128
c. 255.255.255.192
d. 255.255.254.0

Answer 1

The correct subnet mask to include the IP addresses 172.16.31.10, 172.16.30.15, and 172.16.31.206 in the same network is 255.255.254.0, covering the range 172.16.30.0 to 172.16.31.255.

Step-by-step explanation:

You are looking to determine the correct subnet mask for three servers with the IP addresses 172.16.31.10, 172.16.30.15, and 172.16.31.206 so that they are all in the same network.

The correct subnet mask to accommodate the servers in one network would be 255.255.254.0.

This subnet mask allows for a range of IP addresses from 172.16.30.0 to 172.16.31.255, which includes the addresses of all three servers.
