Re: availability of ccTLD zone data

Hi,

There is no way to “require” ccTLD admins to do much of anything other than the technical necessities to publish NS records (etc) in the root zone. However, if you want to pursue this, the right folks to talk to would be ICANN's Country Code Names Supporting Organization (https://ccnso.icann.org/en).

Hello,

ICANN makes available gTLD zone files via the
Centralized Zone Data Service:
https://czds.icann.org/home

This excludes ccTLDs, which generally do not provide
this data to the public.

There are some exceptions: you can AXFR some zones,
and some ccTLD operators provide either the full zone
as open data, or provide domain names only.  But that
number is very small.

For academic research and to further an open internet,
public access to this data would be beneficial.  ccTLD
operators may wish to "protect" this information for a
variety of reasons, yet at the same time there are
several commercial services from which one can
purchase this data, which invalidates any argument
other than "we'd like to make money from selling
access to this data".

Have there been any discussions around moving towards
a required open data model for ccTLD zone data?  Given
that gTLD zone data (including .com) is publicly
available, I think there's strong precedence that
making this data available is not harmful and in fact
in the public interest.
