It would be nice to detect when recursive resolution doesn't eventually either fail (no reverse) or resolution of the reverse does not produce the same IP address as the reverse. For example

1.1.1.1
	campus.example.com.
		1.1.1.1
	synergy.example.com.
		1.1.1.2

in this case 1.1.1.2 is not stable. The idea probably need to be fleshed out a bit, it we do care when the reverse of an IP address does not resolve to that same IP address. Hints at misconfiguration.
