[AusNOG] DNS test tool feedback

[Damien Gardner Jnr]

Yeah, you need to walk up the root tree to fetch the NS (and especially
glue), as using anything else you may not spot issues as the NS records
coming back from your actual servers can overwrite what was initially
learnt from the root servers in cache if the timing (re TTL) is *just*
right..   I've seen quite a few weirdnesses where you lookup NS from the
root servers, and query one of those NS's (NSii? lol) and get a different
set of NS records come back.

It'd be really handy in your output if you make it really obvious if you're
getting different records back from any of the DNS servers. (Maybe you are,
but would be cool if you can, if you're not :) )

 We ran to the sounds of thunder.
We danced among the lightning bolts,
 and tore the world asunder
