Question

The network address of 173.18.0.0/22 provides how many subnets and hosts?

a. 7 subnets, 30 hosts each
b. 64 subnets, 1024 hosts each
c. 16 subnets, 4,094 hosts each
d. 7 subnets, 2,046 hosts each

Answer 1

The network address 173.18.0.0/22 provides 7 subnets and 2,046 hosts each. Therefore correct answer is option d.

Step-by-step explanation:

The subnet 173.18.0.0/22 is configured to accommodate seven subnetworks, with each subnet capable of supporting up to 2,046 hosts.

First, let's calculate the subnet mask for /22. The subnet mask is a 32-bit number that has the first 22 bits set to 1 and the remaining 10 bits set to 0. In binary, this would be 11111111.11111111.11111100.00000000.

With a /22 subnet mask, the network can be divided into 2¹⁰ = 1024 subnets. However, the first subnet and the last subnet are reserved, so we have 1024 - 2 = 1022 usable subnets.

Each subnet can have 2¹⁰ - 2 = 1022 usable hosts. So, the network address 173.18.0.0/22 provides 7 subnets, each with 2,046 usable hosts.
