overlap

overlap is an application that evaluates the relation between two CIDRs.

The relations can be:

• subset: if the network of the first address includes the second one
• superset: if the network of the first address is included in the second one
• different: if the two networks are not overlapping
• same: if both address are in the same network

The program is only intended to work with IPv4 addresses.
