Question

Which part of the ip address does the subnet mask (in binary 11111111.11111111.11110000.00000000) use for the network address?

A. left 12 bits
B. right 12 bits
C. left 20 bits
D. right 20 bits

Answer 1

The subnet mask 11111111.11111111.11110000.00000000 uses the c) left 20 bits for the network address.

Step-by-step explanation:

The subnet mask 11111111.11111111.11110000.00000000 is represented in binary format and consists of 32 bits. The subnet mask is used to determine the network address and host address within an IP address. In this case, the subnet mask uses the left 20 bits for the network address (11111111.11111111.11110000).
