Most of the WMF sites have IPv6 addresses. For example:

(shell)$ dig www.mediawiki.org AAAA
text-lb.eqiad.wikimedia.org. 1393 IN    AAAA    2620:0:861:ed1a::1
(shell)$ dig lists.wikimedia.org AAAA
lists.wikimedia.org.    31      IN      AAAA    2620:0:861:1::2

(shell)$ dig en.wikipedia.org AAAA
text-lb.eqiad.wikimedia.org. 1459 IN    AAAA    2620:0:861:ed1a::1

However, <dumps.wikimedia.org> does *not* have an IPv6 address.

1) REQUEST

It would be very helpful if an IPv6 address could be assigned for <dumps.wikimedia.org>.

Does anyone know to whom I should make the request?
