The `ipaddr.process` method works just like the `ipaddr.parse` one, but it

automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts

on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its

You can match against your own range list by using

IPv6 and IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
