The above is a normal thing to see. The only global scope IPv6 address there is fdda:67d:d74e:4ed1:3ee3:5e26:8a2b:7db4 which is only a valid source address when talking to something else inside fc00::/7, which is nothing on the internet. So the network unreachable stuff you were seeing before should have gone away now. It's not a necessary thing to do, but the only way to completely remove all kinds of IPv6 addresses is to completely disable IPv6, which requires a reboot with "ipv6.disable=1" on the kernel command line.
