I've seen the same thing, and poked around enough to see that the Wikipedia name servers are returning the wrong authority info for these and other queries (it isn't just AAAA - try TXT, SRV, etc.) Some digging through the archives finds this: https://lists.isc.org/pipermail/bind-users/2011-March/083109.html in which the first sentence says it all: "The nameservers for wikipedia.org are broken." And this followup: https://lists.isc.org/pipermail/bind-users/2011-March/083113.html "It's PowerDNS 2.9.22 that is breaking this, and it will be fixed by PowerDNS 3.0 once that's released, and we get around to deploying it." Looks like PowerDNS was in RC2 as of April 19, not released yet. . .
