Abstract
The “dual stack” capability of a network supporting two or more address spaces is used to perform host discovery in the network address space of one network address format using the network address space of another network format (e.g., via a PING sweep in the network address space of the other network format). The host discovery can be performed using addressing in a smaller network address space (e.g., IPv4 network address format) to discover hosts in a larger network address space (e.g., IPv6 network address format), or vice versa.
