This package will not be ported to Python 3. We can do without it – see
if there is an alternative listed in the notes.
If you think it would be good to port it anyway, get in touch with the upstream!
Python 3.3+ includes the ipaddress module, which has been backported
to Python 2 (python-ipaddress).
Packages that depend on ipaddr should consider porting to ipaddress.
