It just does. :) You can go to http://www.DNSstuff.com/info/revdns.htm for an overview of how reverse DNS lookups work. Or, you can use the "Reverse DNS Lookup" at http://wwwDNSstuff.com to check to see if the reverse DNS entry exists for a given IP. -Scott --- [This E-mail was scanned for viruses by Declude Virus (http://www.declude.com)] --- This E-mail came from the Declude.JunkMail mailing list.
