Zeroconf is "zero configuration networking" and that's the application in which IPv6 scope ID is most important--where you want to plug things together and have it "just work". On a network without assigned IPv6 addresses, IPv6 Unique Local Addresses (ULA) are used, and it's necessary to have scope ID look-ups working to be able to communicate to the IPv6 ULA. With nss-mdns working (patched from the above Ubuntu Launchpad bug), it's possible to do: telnet mycomputername.local (it uses a family AF_UNSPEC look-up, which works) But due to this bug, on a network without assigned IPv6 addresses (ULA only) it's not possible to do: telnet -6 mycomputername.local ping6 mycomputername.local (it uses a family AF_INET6 look-up, which doesn't work with IPv6 ULA because scope ID is missing) -- You are receiving this mail because: You are on the CC list for the bug.
