Allow host masks

[mgaitan]

I'm wondering if we could allow a range of IP as a mask. This is covered by the builtin [ipaddress](module.

consider this example

In [8]: from ipaddress import ip_network, ip_address

In [9]: ip_address('178.18.0.23') in ip_network('178.18.0.0/24')
Out[9]: True

In [10]: ip_address('178.18.0.1') in ip_network('178.18.0.0/24')
Out[10]: True

In [11]: ip_address('178.18.0.255') in ip_network('178.18.0.0/24')
Out[11]: True

In [12]: ip_address('178.18.1.1') in ip_network('178.18.0.0/24')
Out[12]: False

that check could complement this line

pytest-socket/pytest_socket.py

Line 182 in edb216c

if host in allowed or (_is_unix_socket(inst.family) and allow_unix_socket):

I could send a PR if you are interested.

@mgaitan Thanks for the interest! Someone started this effort in #73 - did you look at that already?

No, sorry! I will check that and try to help there.
