ok, just checked in r20450, which uses NS queries instead of MX to lessen load.
 Also, I note Dan's selected a new set of domains.

I think the original report is overstated;

1. we have to perform some kind of real lookup.  assuming a.gtld-servers.net
will work is not a good idea, IMO, esp. while Verisign run those machines and
can screw them up ;)

2. this is not a Netgear-type situation.  That was a whole metric crapload of
routers around the world hitting one machine with UDP packets every few minutes.
 This lookup (a) is cached at the local DNS server and (b) only happens once, at
startup time, and will not happen again until restart.   the caching *really*
makes this less of a problem.

Marking FIXED... if anyone disagrees, feel free to reopen.
