All instances in a cluster should have similar view for each other IP address.
For example: say there are two instances in cluster, say instance1 and instance2.
When instance1 lookup instance2's ip address, it gets address a.b.c.d. Similarly
when instance2 looks up its own ip address, it must get back same address, i.e.,
a.b.c.d. If that is not the case, then it may result in issue 1330. Please refer
to issue 1330 for more details.
