[atlas] Thoughts on allowing newer DNS RR queries?

Outside of Atlas I've been doing a few tests to see how well CPE
supports newer RR types. By newer I mean newer than AAAA. I'd like to
do the same with the Atlas probes.

Has there been discussion about being able to issue RR queries of
newer types?

On the query side, the Atlas device only needs to know enough to
encode the type-value which could be supplied as a numeric if
necessary. On the response side, a simple hex dump of the response
would be good enough.

I guess it's sort of a one-off test for most probes because once we
know a probe and its intervening caches does or does not support a
number of newer types, that situation is unlikely to require
re-testing very often. So an alternative might be to make it a
bootstrap sequence that the probe goes thru?

Out of curiousity, how does the probe do the current DNS queries? Is
it via dig or similar or is it coded into a program of some sort?


Mark.
