OT: What sort of nameserver?

[Simon Waters]

Noted a nameserver that does recursive lookups, but doesn't set
"RA" bit on replies.

version.bind queries are "REFUSED".

I'm just being nosy as it isn't my problem, but does anyone
recognise that behaviour?
I'm guessing a non-BIND nameserver or a dodgy proxy.
In future I'll be sure to test recursion by actually asking for
something hosted elsewhere.
