Description
It seems like any other then the last block in an ipv6 address is ignored when trying to assign static IPs.
Reproduce
# create a network with v6 enabled
mava@server01:~/projects/schema-server$ docker network create --ipv6 --subnet fd1a:b128::/32 mynet123
ebba0bf437a9d8f9ff4f1e245c3b09e65cbaa7c58ad235efd7bdd14bb91b0e38
# create first container

docker: Error response from daemon: Address already in use.
Also after removing the u1 container and starting u2 alone the assigned address is incorrect

}
Expected behavior
u1 should have ipv6 address fd1a:b128:5901::101 and u2 should have ipv6 address fd1a:b128:5902::101 assigned.
