I'm uncertain if my use of check on force_ipv4 is valid. When IPv4 isn't forced, that doesn't mean it's not allowed; right?

Thanks for the PR.

There is already a similar PR which tries to address that - #343. We should figure out how to consolidate those two and get it merged.

I personally think approach in #343 is better start since it handles this difference in the function where this problem can arise.

What do you think?

Sorry for the delay. I've added a check for validating IPv6 address on Windows (e105433) and merged changes into trunk.

Thanks.
