I can ping between machines using their autoconfiguration addresses, however, I cannot ping statically assigned addresses. Also, it appears that all of my servers, those set to autoconf and those note, have 2001:4900:1:111::1 assigned to their loopback address. Is this normal? The route on a host looks like: Internet6: Destination Gateway Flags Netif Expire :: localhost.secure-c UGRS lo0 localhost.secure-c localhost.secure-c UHL lo0 ::ffff:0.0.0.0 localhost.secure-c UGRS lo0 2001:4900:1:111:: link#1 UC sk0 2001:4900:1:111::1 my:ma:ca:dd:re:ss UHL lo0 2001:4900:1:111:20 ma:ca:dd:re:ss:02 UHLW sk0 fe80:: localhost.secure-c UGRS lo0 fe80::%sk0 link#1 UC sk0 fe80::212:17ff:fe4 my:mc:ca:dd:re:ss UHL lo0 fe80::%lo0 fe80::1%lo0 U lo0 fe80::1%lo0 link#4 UHL lo0 ff01:1:: link#1 UC sk0 ff01:4:: localhost.secure-c UC lo0 ff02:: localhost.secure-c UGRS lo0 ff02::%sk0 link#1 UC sk0 ff02::%lo0 localhost.secure-c UC lo0
