Using SQL to determine cidr value of a subnet mask

WebAug 30, 2016 · The CIDR notation is calculated from the number of ones in the subnet mask when it is converted to binary. So, for the default subnet mask of 255.255.255.0, it converts to 11111111.11111111.11111111.00000000 in binary. Add those ones up, and you get 24. In CIDR, that would be /24. WebTo use the host's formula in this scenario, you take the subnet mask 255.255.255.0 and convert it to binary. This would give you: 111111111 11111111 11111111 00000000. As you can see, there are eight 0s in the subnet mask. To use this with the host's formula, you would calculate 28 - 2.
