Airport codes in DNS Names
I was wandering and reading on the Internet this morning and I found a reference to a certain ISP that used Three digit airport codes in thier reverse DNS names. This of course made me start to think about other ISPs, that may be doing the same thing. If nothing else this would help get the location of an IP Address to a major metro area. I also think this explains why on a forum post the geo location tool thought I was in San Jose. This is the location of the NAP that my IP address and the last point on a trace route with an airport code in the DNS name. I’ve already found a list of all of the airport codes and I’m going to start incoporating this data into the IP database.
