The timeouts on the reverse DNS lookup are set to 3 seconds, but if there is a timeout, it will try again (either on the same DNS server, or a different one that is authoritative for the lookup). In this case, the responses are coming very fast, but are correct. Doing a manual DNS lookup shows the same results. >My reverse are there Nope. :) >and can be seen with a simple or trace on most remote systems. I can't explain why other servers would be able to get the reverse DNS entry -- it just isn't there. ARIN directs the query to QWEST (SVL-ANS-01.INET.QWEST.NET or DCA-ANS-01.INET.QWEST.NET), but both of those report that the reverse DNS entry doesn't exist. Specifically, they report an "NXDOMAIN" response, which means that the reverse DNS entry doesn't exist. You can also go to http://www.samspade.org to verify that the reverse DNS entry doesn't exist. >Since this subject came up here, I thought I would ask. Am I >missing something here? Yes. You'll need to contact QWEST and ask them why it is reporting that there is no reverse DNS entry for 208.45.107.202. -Scott --- Declude: Anti-virus, Anti-spam and Anti-hijacking solutions for IMail. http://www.declude.com --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] Please visit http://www.ipswitch.com/support/mailing-lists.html to be removed from this list.
