Nope. The datcenter that builders are in has no ipv6 connectivity. All the builders have the normal fe80 interfaces (ie, we don't explicity turn ipv6 off, but nothing gives it a 'real' ipv6 address). ie, here's buildhw-11 (a hardware machine thats a dell 430 blade): 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000 link/ether f8:ca:b8:f7:27:63 brd ff:ff:ff:ff:ff:ff inet 10.5.125.178/24 brd 10.5.125.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet6 fe80::faca:b8ff:fef7:2763/64 scope link valid_lft forever preferred_lft forever here's buildvm-11 (that is a vm on another dell 430 blade): 2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000 link/ether 52:54:00:6f:3d:80 brd ff:ff:ff:ff:ff:ff inet 10.5.125.108/24 brd 10.5.125.255 scope global noprefixroute eth0 valid_lft forever preferred_lft forever inet6 fe80::5054:ff:fe6f:3d80/64 scope link valid_lft forever preferred_lft forever So, I am not sure what could be going on. All builders are also now f31 with the exception of some ppc64le ones that I am still working on moving over. kevin
