+Verify that IPs can be rearrranged using 'ctdb reloadips'.
+
+Various sub-tests that remove addresses from the public_addresses file
+on a node or delete the entire contents of the public_addresses file.
+
+Prerequisites:
+
+* An active CTDB cluster with at least 2 active nodes.
+
+Expected results:
+
+* When addresses are deconfigured "ctdb ip" no longer reports them and
+  when added they are seen again.
