Comment 1 for bug 1490639

It looks like the new release of python-netaddr is the problem

(venv)[derekh@Tea540 iiii]$ cat t.py
import netaddr
print str(netaddr.IPNetwork("192.0.2.46/32").broadcast)
(venv)[derekh@Tea540 iiii]$ pip freeze | grep -i netaddr
netaddr==0.7.17
(venv)[derekh@Tea540 iiii]$ python t.py
None

(venv)[derekh@Tea540 iiii]$ pip install netaddr==0.7.15
Successfully installed netaddr-0.7.15
(venv)[derekh@Tea540 iiii]$ pip freeze | grep -i netaddr
netaddr==0.7.15
(venv)[derekh@Tea540 iiii]$ python t.py
192.0.2.46
(venv)[derekh@Tea540 iiii]$
