add local ip test

[dmxhZGp1c2hh]

If no_local is true, http://127.0.0.1 should not be valid.

If we add 127.0.0.1, then we should check ::1 as well.

@kritik, Yes. So should I wait for merge or create new pull requests?

[kritik]

What I mean is that I don't like this change because it's not domain but url. Do you have this problem in real world?

[dmxhZGp1c2hh]

For example user should provide some callback url (that I will ping after some event). So in this situation no_local option is very helpful.
http://localhost and http://127.0.0.1 should not be valid options.

Yes, but what I'm asking is do you have faced this problem in real world?

[dmxhZGp1c2hh]

Not yet 😄
