is_loopback behaviour differs between ipv4 and ipv6 for IPNetwork #222
Description
IPv4 behaviour:
>>> netaddr.IPAddress('127.0.0.1').is_loopback()
True
>>> netaddr.IPNetwork('127.0.0.1/32').is_loopback()
TrueIPv6:
>>> netaddr.IPAddress('::1').is_loopback()
True
>>> netaddr.IPNetwork('::1/128').is_loopback()
FalseI would expect all of the examples above to return True.
But as you can see netaddr.IPNetwork('::1/128').is_loopback() doesn't.
