Detailed Description

Generic socket address class (IPv4 or IPv6 address & port).

The string representation is "addr[:port]" or "[addr:]port".

In this class, methods which apply to only one generation, IPv4 or IPv6, have a name ending in 4 or 6, respectively. Some constructors implicitly build one generation of address, IPv4 or IPv6, but their names remain IPAddress() without trailing 4 or 6 by design of C++.
