The current SSB protocol is ipv4-only according to the SSB Protocol Guide. We should extend it so it supports operation over IPv6.

Changes in the protocol would be minimal:

  • peer discovery announcements should also be sent to to the all-nodes link-local multicast group FF02::1 (#3)
  • peer discovery messages should support advertising an IPv6 address (caveat: The field delimiter is :)
  • peer discovery listeners should bind to IPv6
  • tcp protocol listeners should accept connections over IPv6

Let's implement it so we have something that works before proposing those changes to the protocol maintainers
