Abstract:
In one embodiment, a subnet mask is automatically determined by a first network node attached to a subnet in a packet communication network. The first network node issues plural communication packets from plural source addresses to at least one address known to be used in the subnet to evoke responses, and based on the presence or absence of responses from the network nodes at the known addresses, the first network node determines the subnet mask which represents the subnet.
