After the initial development of WhatRoute, I became interested in trying to understand something of the geographical locations of the various routers that lay between my computer and the eventual destination of my IP packets. I soon found the CAIDA organisation
at San Diego, CA, made contact with them and was given access to their NetGeo IP address to physical address database. Kim Claffy (kc) and David Moore were very helpful and supportive in these efforts although I dont think they had quite understood the load that would be placed on their servers when they agreed to giving WhatRoute access. Sorry about that.
ceased to maintain their free database and it became less and less accurate. I was in no position to purchase a commercial service for use in a freeware utility, but a little research led me to the GeoLite City database at www.maxmind.com
. WhatRoute currently uses this database and although the results are sometimes inaccurate, in general they are good enough to give a feel for the geography of the Internet.
Many WhatRoute users have requested a higher resolution map than the one I provide in the software. This current release of WhatRoute will pass geographical locations to Apple Maps or Google Maps for a detailed view.
