AddressFamily Comparers
=======================

AddressFamily comparers are simply classes that extend ``Comparer<AddressFamily>``.

DefaultAddressFamilyComparer
^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Behind the scenes ``AddressFamily`` is simply an ``enum``. Typically we're only concerned with ``InterNetwork``, with a value of 2, and ``InternNetworkV6`` which is valued at 23.

The ``DefaultAddressFamilyComparer`` is used to compare the address families of the addresses. No real magic here, we're simply comparing two ``AddressFamily`` values based on their inherit inherit value.
