Detailed Description

Encoding used in BGP update packets to encode prefixes (IPv4 only) for withdrawn routes and NLRI information.

The prefixes are passed on the wire in a compressed format: 1 byte: prefix length L (in bits) n bytes: prefix, L bits (n = (L+7)/8)

Effectively, this class is just an IPv4Net. We only need methods to encode and decode the objects.
