It's not forbidding single label domain names. It's forbidding searches crossing administrative boundaries. Has anything really changed since RFC 1535 was published to make that *safe*? Have 'COM' or '.' in the search list was bad when RFC 1535 was published. Nothing has made having either of them in a search list any better since. With the opening up of '.' to more players has made it worse. > > This section provides a small command line that tests which TLD has > > an A or a AAAA RRset. > > May be a mention of RFC 7085 here?
