At Clearspring we found it convenient to uses the last octet of the IP since that was already unique per cluster (no clusters span multiple subnets [1]). We have on occasion confused ourselves by having non-sequential ids, but it's probably best that those bugs were squashed sooner rather than latter. [1] And yes, this will be a nifty problem when a cluster no longer fits on a single subnet ;-)
