[conspire] Fun <cough, cough, cough> with DNS ; -) ... or ... let you count the ways ... ; ->

So ... *maybe* a fun 'lil exercise/challenge.  ;-)

I was almost thinking of bringing it up at or just before the last
CABAL meeting.  So, ... DNS booboos, troubleshooting, ...

So, quite recently before the CABAL meeting, had encountered ...
well, okay, maybe let's play a game.  :-)

Start, oh, ... say ... here:
wsgba-nno.nabmig.synchronoss.net.
Mmmm... let's say, oh, ... how fast can you find out what, if any,
A and/or AAAA records exist for that DNS name (just to give one a
starting point).  Oh, and ... say from there, how many significant
classes/categories of DNS errors can one find?  Ooooh, game?  :-)
Sure, why not?  How 'bout ...
o +20 points for each significant class/category of DNS errors one can find
o -15 points if you use some on-line web checker thingy
o +5 points for each not strictly DNS but in or closely related to DNS issue
o +20 points for using dig and/or delv
o +10 points for using both dig and delv and stating/showing a good reason why
o +10 points if you use devl but not dig and can give good reasons why
o -10 points if you use nslookup
o +15 points - DNSSEC - show what right/wrong/nothing they're doing there
o +5 points - suggest how they could monitor to detect common DNS errors
o Oh, and there may be a time factor ... they may eventually fix their errors

Tip: you'll probably need IPv6 to fully test their DNS, but you may not
need IPv6 connectivity to The Internet to find all or most all their DNS
booboos (I strongly suspect each of their NS servers with IPv6 AAAA
records is simply single host that's dual stacked with IPv4 and IPv6 - but
I don't know for sure).

So, ... who gets the high score?  :-)  Your opponent is the DNS provider,
their objective is to make your score as low as possible ... they're not
playing a very good game 8-O ... but to give 'em some credit, the did fix
about half of their major DNS booboos since I told 'em about their issues
shortly before the last CABAL meeting ... but, yeah, they still have a
significant way to go on stepping up their game.

Optional - extra amusement.  From more-or-less upstream in their
self-promotional text on 'da Interwebs: "
