I posted this in another forum, but maybe someone here knows the answer?

Is there a way to get a reverse lookup from the entries in the "system folder references:hosts" file?

You're trying to get the CNAME or A-Record from an IP address?

i.e. you want to know who is 17.254.3.183?

If you're using OS9 then you can use WhatRoute http://www.versiontracker.com/moreinfo.fcgi?id=4911

in the "Host" box type in the IP address, select Query, Class=ARPA, Type=PTR (pointer)

And you'll get something like this:

Start: 6/19/01 5:46:03 PM
;; Query: 17.254.3.183 ,type = PTR , class = IN

;; ANSWERS:
183.3.254.17.in-addr.arpa. 86400 IN PTR apple.com.

;; AUTHORITY RECORDS:
17.in-addr.arpa. 86400 IN NS nserver.apple.com.
17.in-addr.arpa. 86400 IN NS nserver2.apple.com.
17.in-addr.arpa. 86400 IN NS nserver.euro.apple.com.
17.in-addr.arpa. 86400 IN NS nserver.asia.apple.com.

;; ADDITIONAL RECORDS:
nserver.apple.com. 432000 IN A 17.254.0.50
nserver2.apple.com. 432000 IN A 17.254.0.59
nserver.euro.apple.com. 86400 IN A 194.151.19.41
nserver.asia.apple.com. 86400 IN A 203.120.14.5

If you have a linux, OSX, or windows box then you can do CLI commands if you want.

A-record, but I need to do it via OpenTransport, I can't use a third-party app (ie WebStar needs to do a reverse lookup, so it's doing so through OT, I want to tell it the a-names but can't find a way of doing that through the hosts file).
