--- Comment #6 from Petr Šabata psabata@redhat.com --- Nothing has changed about my previous comment. IPv6 support in this package is optional. If you want support for it, you can always install IO::Socket::INET6. Optionally.
Adding a hard dependency on it forces it onto people who don't need it and differs from upstream behavior.
If you believe Net::Server users shouldn't have a choice in this matter, the best way would be discussing it with upstream. The package could then follow upstream decision.
I'm not against IPv6, far from it. Just stating the facts.
