Detailed Description

Implements the IpPortFrame class class - A frame for generic network addresses.

IpPortFrames consist of a 2-byte port number followed by a 2-byte IANA address family number plus the address. These fields are stored in network byte order. We only support IPv4 and IPv6 addresses - as the port is mandatory for this object.
