[dns-operations] DNS deluge for x.p.ctrc.cc

[william(at)elan.net]

[Now asking from software engineering perspective... and if this is not 
right list for it - suggest which one would be]

What is a correct way to verify if dns server is recursive from your 
resolver? Is asking info on your own domain from remote nameserver ok
for it? What timeout should be used to decide that there was no answer?

And BTW - what is correct way to deal with queries at the dns server side?
Lets assume we want appropriate security applied and have dns server only 
answer regarding netzones it serves or on behalf of clients on pre-set 
(local) network. If query comes in for non-served zone from remote net, 
should dns server simply ignore the query and not send any answer?
