Question About nslookup

[Matthew Thompson]

As I understand the RFCs the default is to initially use UDP - if the
response is too big you'll get a reply reporting that it's truncated and you
can then resubmit - if necessary - with TCP.

I'm sure someone will correct me if I'm wrong ;o)

M at t :o)

A quick question about nslookup. Does it use UDP or TCP by default? If it
uses both, under what conditins does it use either kind of socket?

Correspondingly, could someone point me to the portion of BIND code, where
the incomingg messages from nslookup are accepted, also what kind of socket
does BIND listen on, for requests?

Thanks
