    It is easy to check for this mismatch

    As an example of how easy it is to check for consistency between the delegated-from zone and the delegated-to zone take a look at http://www.paf.se/domain/ [www.paf.se]

    By-the-way, that checking is done using only normal net operations, no zone transfer is performed.

    Let's see, Patrik Fältström, is doing 10,000 such checks each day - at that rate he could check the validity of the roughly correctness of the delegations for all of the roughly 250 TLDs (including the ccTLDs) in much less than an hour.

    In fact, somebody over at ICANN could write a simple script to push all the TLDs through Patrik's script every now an then.

    I have tried to test my own domain with that tool, and it gives warnings about the fact that some of my secondary NS and MX (which mostly are provided by friends, so I don't control them) do not have correctly configured PTRs.

    Which brings me to the point that if direct resolution often has errors, reverse resolution almost always has errors, because while usually the final user controls the domain name zone, it does not control the reverse (.arpa) zone. And your upstream provider usually couldn't care less about configuring PTRs for you.

    This could be an interesting topic for reflection about the way IP addresses are allocated and managed :-)
