Yeah it's a huge source of problems. If you are outside the US your IPv6 prefix is never gonna be correct in every GeoIP database, even if you send a request to have it corrected, so you sometimes get geoblocked and other sites just block you because it sometimes gets classified as VPN.
I agree. GeoIP was never a good idea, but here we are. Any ASN could be broken up and routed wherever (and changed) but it's still far too prevalent.
I did it by acquiring my own AS number and prefix, allowing me to set the geofeed, and announcing it via public BGP from a box in a data center. Took a few days for most things to pick it up the geolocation.
Sounds (labor and money) expensive.
What's the best way to spoof geoip on ipv6 ?
It's the same as IPv4 (tunnel) except as mentioned above its still hard to get an IP with the right label
