Detailed Description

A version independent IP address.

Warning

This is deprecated and scheduled for removal in 2025.

This is inspired by asio::ip::address, but it also adds port() from asio::ip::endpoint and a few other observer member functions i.e. it fuses ASIO's many types into one.

The reason why is that this type is a simple wrap of struct sockaddr_in or struct sockaddr_in6, it doesn't split those structures into multiple C++ types.
