IPv6 DNS records with dns_*() functions

Hi,

I noticed the DNS record lookup functions (in the documentation) all refer
to AAAA as an IPv6 type record. Actually, AAAA is obsolete now.. Of course,
in PHP it would be very wise to support AAAA, but the official type is A6.
You may want to start supporting that in the dns_() functions, or if it
already works, you may want to update the documentation on these functions.

That's certainly doable, but to help track it, could you create a feature
request for it at bugs.php.net?

Also, links to any RFC or other documents pertaining to implementation would
be helpful.

I'll add this into dns_*() for PHP 5.1.0 and to Net_DNS for the next release
of that package.

Oh, okay... so no need for me to create a feature request?

It is actually the other way around. AAAA is the official standard and
A6 is deprecated for years.

hmm, from http://www.dns.net/dnsrd/rfc/ i get the same idea, yet on other
websites it is mentioned sometimes that A6 is the "new" AAAA.. .pretty
weird..

if both are used in practice tho, i think PHP should parse them both, don't
you think?

I saw one reference to preferred order of resolution being A => A6 => AAAA
which implies that A6 has a higher order of preference than AAAA.  Also, the
DNS record type number for A6 is higher than AAAA, again indicating that
AAAA preceeded A6 in adoption.

In either event, as Ron states, there's no harm in covering 'em all.
