What's keeping test.drugabuse.gov from an A

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