.. note::
To sort networks with :func:`sorted`, :func:`min`, :func:`max` and
other tools with a *key* argument, use the :func:`operator.attrgetter`
function to extract the relevant fields::
>>> from operator import attrgetter
>>> s = [IPv6('::1/128'), IPv4('255.255.255.0/24')]
>>> sorted(s, key=attrgetter('version', 'network', 'netmask'))
[IPv4('255.255.255.0/24'), IPv6('::1/128')]
