What's keeping webmail.wy.sk from an A

  1. webmail.wy.sk is an alias of roundcube.sk, which has no IPv6
    webmail.wy.sk is a CNAME, so it can't also have its own AAAA record. Ask whoever runs roundcube.sk to enable IPv6 there — or replace the alias with the A and AAAA records they give you. Why some hosts don't offer IPv6
