I hadn’t put that quite together. I wonder how many people would value IPv6 if they knew it meant less CAPTCHAs.

I'd imagine that to be short lived. IPv6 having such a huge address spaces means the IP reputations are even more worthless than IPv4 so eventually the bots would use it too, and if the ratio of bots to real users become too high sites may refuse IPv6 traffic altogether.

  It’s a little different though in that rather than an IP having a bad reputation, it’s usually a /64. That’s how I have seen IPv6 reputation managed since it’s a common network slice & NAT is not really used anymore.

  You can block ipv6 /64 subnets just like you can block IPv4 /32 IPs.

  Ooof that's an ugly thought. But I think "refuse IPv6 traffic altogether" is not possible for any consumer site. Per the article, there's 40% adoption of IPv6 now and it's only growing. Major parts of the world rely on IPv6 working right. I guess sites could go IPv4-only but given how many other problems there are with IP reputations, that'd be awfully dumb.

CAPTCHAs are the main reason I turned IPv6 on. No idea if it will actually help in practice, it's hard to measure. The other Starlink hassle is the geocoding for user IPv4 addresses is wildly wrong. I'm in Grass Valley, CA near Sacramento but sites all think my IP is either in Seattle or Los Angeles, depending on the week. This makes streaming services a huge PITA, I have to jump through hoops to convince them I'm in the Sacramento TV market about once a month. IPv6 could help with this too, Starlink could give out more precisely geolocated addresses. Not sure they're doing it though, all I see are IPv4 addresses in the geocoding feed: https://geoip.starlinkisp.net/feed.csv https://geoip.starlinkisp.net/feed.csv

  I was on a cruise ship in the Caribbean for a week just last month and I purchased the starlink powered internet package. Looking at my IP data, location info showed that I was actually in Dallas, Texas. Very sad!

  Or, as an alternative, we try to convince people that geoIP lookups are at best uncertain and at worst actively misleading -- and perhaps shouldn't be taken at face value. I personally think this would be a great thing. For paid services that allegedly need to know where you are geographically located, use your billing address. For advertisers it's one less bit of useful information...

    I agree! Now please convince Youtube TV, Hulu, and friends. YTTV at least will prefer your phone's geolocation to the IP address, that's how I "check in" to my metro every couple of months.
