Question



A class B network on the Internet has a subnet mask of 255.255.248.0, what is the maximum number of hosts per subnet?

A.

1022

B.

1023

C.

2046

D.

2047

Correct option is C


1. Subnet Mask Calculation:
· The subnet mask 255.255.248.0 in binary is 11111111.11111111.11111000.00000000.
· This provides 21 bits for the network and 11 bits for hosts.
2. Calculating Hosts:
· Number of host bits = 11, so maximum hosts per subnet = 211 - 2 = 2046.
Information Booster
· The -2 accounts for the network and broadcast addresses.
· Class B networks typically use the first two octets for the network portion.
