Follow up to #46924, fix massive spurious failure when starting docker

It seems using `fe80::/64` causes `docker start` to fail with "Address already in use". Try to change to a unique local address range instead.

`fe80::/64` is a link-local address (similar to `169.254.0.0/16` in IPv4). Let's try to use a random "private network" address to see whether that fixes things.
