An organization is granted a block of classless addresses with the starting address: 156.78.51.0/22. They want to create subnets of size, 512, 256, 128, and 128.

What is the subnet prefix for each subnet?

512 prefix = ________

256 prefix = ________

128 prefix = ________

128 prefix = ________

Solution

1022 =156.78.48.1 - 156.78.51.254

512 prefix =156.78.48.1 - 156.78.51.254

256 prefix =156.78.51.1 - 156.78.51.254

128 prefix =156.78.50.1 - 156.78.51.254

128 prefix =156.78.50.1 - 156.78.51.254
