Return Value

Network mask or null if address doesn't belong to classes A, B or C


Each IpAddress belongs to one of the 5 classes, A, B, C, D or E. D network class are multicast addresses and E is experimental class. Because D and E are not "real" network classes and as such don't have a network mask, only classes A, B and C will return a valid subnet mask. Classes D and E will return a null reference.
