I don't get the cynicism.  It's good to have an IPv4 only machine in 
the set.  There are many name servers that will try the AAAA and fail 
and then give up on the A record.  Until the v6 network is solid 
and/or until we rid the network of old code it's good to have at 
least one v4-only NS everywhere.

Did you try discreetly asking ARIN to fix this?  Perhaps at noc at arin.net.
