I haven't yet seen a commercial service selling ccTLD data that is especially accurate (neither many expired, nor many missing domains). Do you actually know of any ccTLDs that sell the zone data to a commercial service? While I agree that not disclosing the zone data is mostly futile, I don't expect that ccTLDs (or their lawyers and national regulators) are likely to yield to reason in the near term. Setting aside the small handful of ccTLDs that have agreed to provide first hand data, my secondary source efforts net for example: ccTLD known total %known no 747951 848598 88% uk 9613373 11045559 87% cz 1256340 1471541 85% be 1398804 1744859 80% hu 689242 861152 80% de 13135627 17473858 75% at 1117475 1493828 74% eu 2766671 3710091 74% pl 1877283 2504545 74% za 1027102 1373287 74% br 3729531 5053100 73% it 2519191 3487431 72% es 1292153 2011933 64% nz 462626 ~750000 61% au 2506080 4199392 59% mx 649342 1350270 48% cn 2219800 ~17900000 12% ... It looks like typically ~75% can be found without a feed (I only collect data on DNSSEC signed ccTLDs). The totals from variously recent reports of total counts by the ccTLD. The .cn and .nz numbers are particularly rough. > Have there been any discussions around moving towards a required open > data model for ccTLD zone data?

I concur that this is not a matter that IETF can do anything about. If you do manage through other channels to convince more ccTLD management to share data, that'd be great of course. Good luck. -- Viktor.
