This reverts commit feca39de88fa3313b1f5c33ced3ace221c6a2b82.
After discussion with @mcches, we established that:
a) IPv6 is supported by conicidence, is partially completed, we don't want to ship that.
b) There is a bug which treats localhost communication as non-localhost.
c) We don't want to introduce localhost communication into a router (top.rs) and want to keep it local to the host, as an OS would.
