Shalom!

First of all, I've been reading and re-reading TFM; however, something
eludes me, apparently.

Our site runs several proxy/caching servers for the Israeli university
system.  To my dismay, a number of universities do not have IN PTR
entries for DHCP-assigned IP addresses, making it impossible for Analog
to resolve them.  As a result, our Organizations Report shows 24% as
"unresolved numerical addresses".

"Other reports" explains the difference between the Host and Domain
reports (which don't interest us), and the Organization report (which is
extremely important to us).  That is, the Organization report is
important in terms of second-level TLDS, i.e., 

   tau.ac.il
   technion.ac.il

but without the overwhelming granularity of hostnames or department
subnets.

When Analog performs its DNS lookups, it writes the results to our
dnscache file.  Unfortunately, those unresolvable hosts result in
entries of the form

   <timestamp> <IP address> *

which end-up being reported/displayed as "unresolved numerical
addresses".

As a workaround, I've been experimenting with using HOSTALIASes, along
the lines of

   HOSTALIAS REGEXP:\<(132\.(66|67)\.[0-9]+\.[0-9]+)\> tau.ac.il

for all our universities' subnets.  Should I be using ORGALIAS, instead?

Q:  Can I use this method (or other ones) to do away with the need for 
    DNS lookups?

If so, how?
