[PLUG] cname lookups

["Sean C. Sheridan" <scs@CampusClients.com>]

Ok, forgive the noob question...

I'm trying to find a way to generate a list of servers on a particular
domain.  In my mind the records I need are cname records.  But I can't
seem to generate a meaningful response...

By way of example, let's try Upenn.

I am trying to locate domains such as:
isc.upenn.edu
www.cis.upenn.edu
www.rad.upenn.edu

Following the examples at:
http://www.freebsdhowtos.com/62.html

I am unable to use nslookup, dig or host to find the records I need.


So I try a variety of things like:
host -l -t any upenn.edu

It tells me penn uses a name server at udel.edu
dns2.udel.edu

so I try:
dig dns2.udel.edu upenn.edu axfr

but get no love.

This fails with no response:
host -l -t cname upenn.edu

One approach that does work is to search google.  A search for
"*.upenn.edu site:upenn.edu" yields a list of domains, but surely there is
a better way using dig or host.

Any thoughts?
