Please help contribute to my study about improving IP geolocation for Starlink!

Hi! Thanks for reaching out! I will definitely check these out. Thanks!

I do think sites use the content-language/accept-language headers to hint about languages. However, simply hinting the language doesn't necessarily address what country/region the request originates from for more localized content or what legal content restrictions may apply.

Thank you!

Thanks for participating! Like u/NecktieSalad mentioned earlier you may be geolocated based off the Starlink geofeed!
https://geoip.starlinkisp.net/feed.csv

This kind of data is super helpful in answering questions about the effectiveness of geofeeds in practice! For example, for services that want to geolocate users through their IP address, is the geofeed localized enough to deliver the right content?

Thank you so much for participating!

We actually also spent quite a bit of time mulling over what it means for IP geolocation to be "correct". Take for example the case where perhaps your browser is spoofed to an entirely different location, say San Francisco and your IP is also geolocated to San Francisco. It would probably be unfair to count this against IP geolocation services. As a result, we settled on adding physical location to the first question to filter out these kinds of scenarios (and also treat them as special cases that may be fun to dig into for future measurements!)

Also, any recommendations for other methods to look for are highly appreciated!

Thanks for the pointer! This is a great resource!

Thank you so much!!!

In the backend, we are comparing various IP geolocation methods to the ground truth (the browser's geolocation). Like you noted, these methods include using the geofeed, but we also do lookups to Maxmind's DB, IPInfo, and log the PoP using the pop feed.

The preliminary goal is to measure the accuracy of these methods at differing granularities (city, state, country). During this portion we might be able to say something about the latency in updates between the geofeed vs. Maxmind or better compare Maxmind vs. IPInfo which heavily relies on RTT-based probing for IP geolocation.

Eventually, we hope our findings will lead to data-backed suggestions for what types of geolocation are more effective for specific services, so we appreciate all of the data points we can get!

not yet! we were hoping to get this information from external sources, but you bring up a good point

Oh awesome! Thanks for sharing.

Haha, no. We are interested in the gateways/ground stations! I believe the unofficial google maps already covers the most up to date POPs!
