Does swarm support IPv6 network？

[HappyThis]

System information

Swarm version: Version: 0.5.8-unstable OS & Version: Linux ubuntu 18.04 Commit hash : (if develop)

Expected behaviour

I started several swarm in several docker containers of the IPv4 server, and swarm can work. But when I use docker to deploy swarm in IPv6 server, swarm can't work。

1.create ipv6 network: docker network create -d bridge --ipv6 --subnet "fd00:daad:beee:1::/64" FLChainNet 2.create docker container: docker run --name=node1 --network FLChainNet --ip6="fd00:daad:beee:1::101" --hostname=node1 --rm -it node:v3 3.Starting swarm in docker： swarm --bzzaccount 0x865932603FC99595775323476346b121dA8B65d7 --datadir /home/geth/data

Actual behaviour
