[dns-operations] Site or service to test resolvers?

[Thomas Steen Rasmussen]

Hello,

I seem to remember a site or service where you could test your 
configured recursive resolver for all kinds of stuff - the basics like 
dnssec and ipv6 support of course, but also source port distribution, 
txid distribution, and a whole bunch of weird edge cases to check for 
rfc compliance.

I've searched but I can't seem to find it again, does anybody know what 
I'm on about?

I know about OARCs port randomness test, and a few other ones that check 
specifics, but I was sure there was one that did a thorough all-round 
test of the configured resolver. Any hints?

Thanks! :)
