All connection initiation should be exclusively mediated through the DNS and

The reason I introduced the term signalling was precisely because setting up a

Would that include connections to one's DHCP server, SLP server, default

A prediction: Sooner or later, IPv4 addresses become so scarce that
renting a colo server with IPv4 becomes more expensive than IPv6. When
that happens, a few NAT-hating spoilsports will set up the first few
IPv6-only servers and a year later, the transition to IPv6 starts.
I wonder what kind
