Ask HN: Accuracy of ip to geo location?

I don't know about in the USA, but given the types of consumer access in use today, I wouldn't rely on it much beyond the country or perhaps state/province level.

For consumer level ISP's, you're likely to just get the location of the ISP headquarters.

If you need more accurate user location, I'd suggest looking into device location APIs - they aren't available all the time, and the user can reject/deny the request, but if accurate location is important and actually gives benefit to the user, that's likely a better solution.

Right sub-continent?

Can go as bad as 50km off in a country with good infrastructure (United Kingdom).

they could be highly inaccurate. i had experience of the actual location being as far as 500 miles away from the IP's location

I was hoping to get at least within 60 km
