IPv6 compressed notation and replication

If the ring is created with IPv6 in compressed notation where the address has a single contiguous group of zero fields represented as a double colon "::''. It appears that the replicator has issues because rsyncd sees two sets of "::" when trying to replicate to another device. In rsyncd the word after the "::" is the rsyncd module entry. Therefore it gets confused, I believe.

The problem goes away once the ring is recreated without a single contiguous group of zero fields being represented in double colon "::''.

Example:
==========
BAD RING
==========
root@swift-ip6:/etc/swift# swift-ring-builder object.builder

262144 partitions, 3 replicas, 4 zones, 4 devices, 0.00 balance
The minimum number of hours before a partition can be reassigned is 1
