feat: support cidr blocks in --allow-hosts

[emhagman]

This feature allows --allow-hosts to support CIDR blocks. This is useful inside Docker since different services can get any range of IPs (typically on 172.17.0.0/16 or 172.20.0.0/16) and pytest-socket doesn't support hostnames.

I can also add hostname support if we think that is useful.

Any chance of getting this merged? Would absolutely love this feature for our CI pipelines!
Alternatively #80 would also solve this issue for us.

We've been pointing to our fork. Unfortunately it doesn't seem these pull requests are looked at. We have a case where we are going to need the hostname support as well in the near future

They do get looked at - this specific one is failing a check which would need to be resolved.

A complexity check off by one...? OK, I can fix it. I appreciate your work, it just would have been nice to get an update or hint that we'd like to merge it

@miketheman @emhagman how could I help to get this merged? Should I open a new PR fixing the conflict ?

[djanowski]

@miketheman Any chance of getting this merged, or @mgaitan's alternative #185?

[emhagman]

I'd just take #185 over this. Don't want to fix conflicts, this has been open forever. We've just been using our fork forever now.
