Only exactly one address on dev is supported

[kroese]

I always get this error:

      if len(addr['addr_info']) != 1:
           raise ValueError('only exactly one address on dev is supported')

Because I have an IPv6 interface in Docker. When disabling this check, the container continues too boot without any issue, because the first interface happens to be the correct one.

Would it be an idea to always select the first address instead of raising an error?
