icanhazip.com looks even simpler on the face of it but there's always shenanigans behind the curtain:

This would just be another "general good of the internet" service.

RIPE for example run.

Atlas: A cooperative service for internet reachability and measurements. - https://www.ripe.net/analyse/internet-measurements/ripe-atla...

DNSMON: Monitor the root and TLD's and other key internet domains. Does so from many locations so as to test anycast issues. - https://dnsmon.ripe.net/

RIPEStat / BGplay: Debug and examine internet reachability issues. - https://stat.ripe.net/ - https://stat.ripe.net/bgplay

And volunteer resources to help to run other things, like https://www.as112.net/ that sinks all the PTR lookups for RFC1918 that leaks to the internet, among other things.

That doesn't seem too surprising to me and should ensure that the site can be run sustainably without burning out volunteers.

My ISP publicly supports IPv6, but I've never gotten it to work properly, and none of the technical support I've been able to been forwarded to knows what's wrong either. Colleagues using the same ISP has the same problem, so doesn't seem to be an isolated incident.

I'm sure there are more people out there in the same situation.

My mobile connectivity comes via Mobile Vikings which are now part of Proximus - also IPv6 there, and I love their excellent service.

But it could also be APNIC, they put out a lot of observational reports too, so it could fit with my perception of them. Maybe LACNIC or AfriNIC wants to do something to raise their profile?
