Either way - it breaks Sendmail, some versions of Exchange, and possibly other MTA's. The proper answer to a non-existent AAAA record is NOERROR, with ANSWER 0.

Hanging or refusing to answer doesn't result in another attempt to look for an A record since the name server failed to respond to a valid query. Given that the whole point of the domain is to enable email printing, HP isn't making it easy.

    Dear HP:

    If your not going to support IPv6 can you at least not return
    SRVFAIL when asked for an AAAA record:


They aren't. Your resolver is - or at least, that's what it looks like for me.

Sending an AAAA query to their nameservers times out for me - no response at all. Sending the same query through certain resolvers (eg, Google) seems to result in the timeout being turned into a SERVFAIL.

$ dig AAAA onramp01.hpeprint.com <http://onramp01.hpeprint.com>

;; global options: +cmd
;; connection timed out; no servers could be reached


Same via Google :
$ dig AAAA onramp01.hpeprint.com <http://onramp01.hpeprint.com> @8.8.8.8 <http://8.8.8.8>

; <<>> DiG 9.8.4-rpz2+rl005.12-P1 <<>> AAAA onramp01.hpeprint.com <http://onramp01.hpeprint.com> @8.8.8.8 <http://8.8.8.8>
