This assumes that one may use an ULA (IPv6) to reach a globally routable (IPv6) address. In other words, that someone has introduced some kind of NAT or transparent proxy in the middle. I'm not so gullible as to believe that nobody will ever try to implement this, but... if some network administrator really wants to provide “transparent” IP-layer access to the globally routable IPv6 Internet, shouldn't (s)he hands out public IPv6 addresses/prefix(es) to his/her users, possibly in addition to ULAs? What would be wrong with the IPv6 stack throwing an unreachable error whenever an application tries to send a packet/connect to a global IPv6 address while its socket is bound to an ULA or while the host has no global (or at least has no non-ULA-nor-link-local) addresses? -- Rémi Denis-Courmont http://www.simphalempin.com/home/
