Detailed Description

A generic socket address class.

This class uses the addrinfo list to store socket multiple addresses in a protocol and family independent manner. Hence, this address class can be used for ipv4 and ipv6 sockets, for assigning connections to multiple hosts, etc. The address class will call the resolver when passed host names.
