Slightly misleading title, this is more “getting to the IPv4 internet via an IPv6 tunnel through a VPS”. Also just called 4in6.
Interesting nonetheless!
We find at our ISP that if we break something with IPv4 we experience a very different type of support issue to if we break IPv6. Breaking v4 results in, broadly, a pretty hard “down” state. While folks are unhappy, it is at least simple. Breaking v6 results in weird, and a partial down, which manifests for the users as partial outages, slow starts due to fall back, etc. Especially if their gateways believe there is v6 when there isn’t.
