Since David didn't explain how you get from here to there, I'll take up where he left off. The way you calculate the suffix notation for a given netmask is to convert your netmask into binary and count the 1's. For your Class "C" network, the netmask is: 255.255.255.0. If you convert that to binary, its: 11111111.11111111.11111111.00000000 If you count the 1's, you will find that there are 24 of them, so the suffix notation would be "/24". If you were to subnet using a 255.255.255.240 netmask, the binary representation would be: 11111111.11111111.11111111.11110000 In this case, there are 28 1's, so the suffix notation would be "/28".
