Sorry, forgot to attach the patch.
Is this why you have some blind excepts?

We should get an upstream bug filed on python-netaddr about this.

Apparently it's already been fixed for the next release.
IMHO it's not much of an issue for us, because the exception gets caught
in parse_ip_address and that's currently the only place where
_IPAddressWithPrefix is used.
Shoudl parse_ip_address() raise an exception on bad data rather than
returning 0.0.0.0?
I've been down that road and it would need a rewrite of the fragile IP
address handling logic of ipa-server-install, which is something I'd
rather avoid.
>>> installutils.parse_ip_address('355.555.3.3')
_IPAddressWithPrefix('0.0.0.0')
or
>>> installutils.parse_ip_address('192.168.0.1/55')
_IPAddressWithPrefix('0.0.0.0')
Should it disallow net addresses like 192.168.0.0?
If you mean network and broadcast addresses, it probably should. It
might be a good idea to disallow localhost, multicast and/or link-local
addresses too.
