InterMapper uses a shorthand notation to represent an IP subnet's information. The number in the "/xx" shorthand stands for the number of bits (technically, bits set to one) in the subnet mask. The convention is always to start at the left end of the 32-bit subnet mask. The table below shows the correspondence between the "/xx" notation and the actual numeric representation.
it_waaznt_me said:192.168.0.20 is a class C address ... In a class C address, the first three octets represent the Network Portion and the last octet represent the host portion. So 192.168.0.0 is the network and 20 is the host.
