A computer with the IP address of 134.67.89.12 and a subnet mask of 255.255.0.0 is on the same network with which of the following systems?

A. 134.76.89.11

B. 13.4.67.34

C. 134.67.112.23

D. 109.67.45.10

C. 134.67.112.23

Explanation:

A computer with the IP address of 134.67.89.12 and a subnet mask of 255.255.0.0 has a network address of the form:

134.67.0.0

This is obtained by retaining those sections of the ip address for which the corresponding subnet mask element is 255. In this case subnet mask is 255 for ip address components 1 and 2 or in other words the network address contains 134.67. Among the given options only 134.67.112.23 has the same network address.
