[e2e] Mapping IP Addresses to Geographic Location

[Shane Cruz]

I am currently in the process of researching the possibilities of 
generating a mapping from IP addresses to geographic locations.  I am 
starting by analyzing various techniques and methodologies (such as 
parsing WHOIS and traceroute requests) in order to get a good idea of the 
accuracy that can be provided with these methods.  In order to create a 
useful analysis, I need to obtain a sizeable data set that maps IP 
addresses to actual location information (such as a zip code).  Does 
anybody know of a good way to obtain this type of data?  Currently, I have 
created a site that has a simple form for users to enter their zip code so 
I can store the IP and zip.  For more information about this research, and 
to help me in collecting this data, please visit:

Thanks for your help and suggestions!
