RE: Supernetting or CDIR

Supernetting.

A supernet is an Internet Protocol (IP) network that is formed from the
combination of two or more networks (or subnets) with a common Classless
Inter-Domain Routing (CIDR) routing prefix.

The process of forming a supernet is often called supernetting, route
aggregation, or route summarization.

One benefit of CIDR is the possibility of routing prefix aggregation (also
known as "supernetting" or "route summarization").

Take, for instance, a class B
mask of 255.255.0.0. If one borrows 2 network bits, the mask changes to
255.252.0.0; this is called supernetting. If on the other hand one were
to borrow two host bits, the mask would change to 255.255.192.0, and
this is called subnetting.
