Does your old machine have an IPv6 address? Does your new machine
have an IPv6 address? Can you ping6 one machine from the other?
% ip -6 addr
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qlen 1000
inet6 2001:770:1d5:ffff:ffff:ffff:ffff:ffff/64 scope global dynamic
valid_lft 86396sec preferred_lft 14396sec
inet6 fe80::62a4:4cff:fe5f:1257/64 scope link
valid_lft forever preferred_lft forever
Note the global address for eth0. If you can't ping6 the other
machine, then there's probably no IPv6 connectivity. All services
should default to IPv6 and fall back to IPv4 if unavailable.
