 Relays don't extend via IPv6, so any outbound IPv6 connections you see on
 an authority are reachability tests.
 (We'll need better reporting of IPv6 once we do IPv6 extends, I added
 #29113 so we remember to add them to the heartbeat.)

 Any inbound IPv6 connections you see are from clients using your authority
 as an entry. (Which should be rare.)
