[tor-relays] Improving Relay IPv6 - RIPE Grant

[Paul Geurts]

hi Johathan,

this question was already addressed last week by Teor.
email on this mailing list doesn't always seem to arrive in a logical
sequence.... possible due to spam filters and so on.

We won't be disabling IPv4 on relays any time soon.

The RIPE grant covers IPv6 address autodetection and self-testing.
If the feature is reliable enough, we may turn on IPv6 on dual-stack relays
by default. (When autodetection and self-testing both pass.)

We don't have any plans to disable IPv4 on relays. We'd need most relays
to be dual-stack first. (Or we'd need research about privacy in non-clique
networks.) And we'd need to write code that allows relays to turn off IPv4.

When that's all deployed, we would have to make an engineering decision
about the capacity of current IPv4-only relays, and the potential capacity
of IPv6-only relays.

One possible transition strategy is to allow IPv6-only bridges and exits.
But to do that, we need more dual-stack guards and middles. That's why
we are improving support for dual-stack relays with this funding.
