What's keeping cntyalerts.com from an A

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