Search Again: Re: Assistance request From: Jeff Folk Date: Thursday, March 6, 2003 Time: 12:13:12 pm Interesting... There appears to be a loop in the reverse lookup: Reverse DNS for 64.215.249.70 Generated by www.DNSstuff.com Country: UNITED STATES Preparation: The reverse DNS entry for an IP is found by reversing the IP, adding it to "in-addr.arpa", and looking up the PTR record. So, the reverse DNS entry for 64.215.249.70 is found by looking up the PTR record for 70.249.215.64.in-addr.arpa. All DNS requests start by asking the root servers, and they let us know what to do next. See How Reverse DNS Lookups Work for more information.
