you should also mention that there are views validating the format of
zonefiles has no technical value, is not needed and can therefore be
skiped.

Technical stability of DNS relys much more on the realtime performance of
the related server and a timly and redundant answering from different
places in the Internet. These things have nothing to do with zonefile
information but with long term monitoring and underlying network
infrastructure. But even this is in my opinion up to the operator of a TLD
and his community.

The only database which IANA has to maintain is the database who operates
which TLD and what are the related nmameservers. For DE this information is
DENIC and a set of nameservers. To check the operational status of our
nameservers before entering them in the IANA database you simply has to ask
them if they felt authorativ for .de (dig @dns.denic.de .de). I am not
aware of other databases which IANA maintain and which they have to check
for accuracy.

If a ccTLD manager wants to optain additional service from IANA like
assistance in error checking then it has to be discussed and can be done as
long as it didn't took too much ressources. For professional assistance
these kind of consultancy services should be left to others like Men &
Mice or others who offer these kind of services on a professional
commercial base.

As Men & Mice is a commercial company offering DNS configuration assistance
I am sure that they will welcome your support for their service ;-).

I am sure that you have also learned from that survey that the .DE-zone is
quit healthy and thats why we are doing some checks similar to those I
discribed above. But we are doing this without checking the zonefile as
this - as I pointed out earlier - not needed for the check of DNS quality.

I am not really convinced. Usually one tries to have a balance between the
benefits and the costs of something. Currently a gTLD-level and a lot of
ccTLDs there are no checks at all when a domain is inserted in the TLD.
DENIC does at least check our delegated domains for nameserver consitency
but we didn't check if siemens.de or ibm.de are doing this also. I have
some understanding that IANA does also check nameserver consistency at
their level and I would recommend to siemens.de and ibm.de to do that also.
But I don't think it's DENIC's task to enforce this within siemens.de and
ibm.de and I don't think it's IANA's to do so for .de.

Historically the DNS software was unable to supress unsolicited
zonetransfers and the TLD managers were not asked (at least not between
1994 and now, when I am operating it). You shouldn't interpret this a
cooperation.

As you have no access to our database it is unclear to me how you want to
perform checks if the zonefile we produce is reflecting our database
correct.

I think you should also point out in your summary that also while some
(Stuart) suggested to performe these checks periodically. Some (CENTR,
LACTLD, ccTLD constituency at their meeting in Bucharest, and others on the
lists) suggest to stop checking the zones immediately.

One big step to improve DNS data quality is to proceed changes in the root
much more timely.

As this issue is very important for ccTLDs I would also recommend not to
decide things without their support.
