Docker swarm over IPv6

I am trying to run Docker Swarm on 3 nodes with IPv6 addresses.

Having created the swarm, I specified the IPv6 address as the advertising address and now had logs on all 3 nodes filled with these messages:

Mar 24 22:17:10 cmd dockerd [3463]: time = "2017-03-24T22: 17: 10.183319197Z" level = error msg = "Could not join member list [IPv6 address here] on retry: 1 error ( s): \ n \ n * Could not resolve IPv6 address here: too many colons in the IPv6 address here

At the same time, worker nodes have joined the cluster and the stacks are deployed (well, the overlay network doesn't work as expected, but that might be a separate issue)
