I agree that having a way for the server to signal its IP-addresses to the client is very important. Even in the v1 of Quic.

Otherwise, Quic migration will hardly be effective.

To easily deploy Quic behind a load-balancer one simply assigns unicast IPs to the servers and lets Quic announce these (v4 and v6) IPs to the client as "preferred address". Then the client can migrate by using the preferred address. There needs to be a way to announce the preferred address in both v4 *and* v6.

This should address Scenario 1 and Scenario 2 that @plakhera is describing.
