Geolocation of BGP Automous Systems

Question

Hi friends I've been looking around for the past few days on a way to find the geolocation of the BGP AS's, preferably through the use of some API. I've been using the ripestat API for the majority of my work on this, but it comes up inconclusive on some of the AS's, for example AS 10000. RIPE tells me the location is in JP. Which is sort of fine, I just would like to narrow it down more to like a city / postal code / etc if possible. Is there another API suited for this? or is it just a manual task of fixing all the information once gathered.

Alternatively, if it is possible to grab the IP address of the actual AS itself, and not the range, that would likely work as well.

Answer 1

IP Geolocation isn't nearly accurate enough to pinpoint an IP to a specific City/ZIP code. In many cases, IPs from the same block will be used across a large area in an ISP's control, so it's not possible to be very accurate. Autonomous Systems don't really have "an IP", as there's no one specific location of them.
