[db-wg] Question regarding delta between "delegated-ripencc-extended-latest" and Whois output

Dear RIPE DB mailing list people,

we, the IPFire development team, just bumped across an IP address somewhere
in the 51.15.0.0/17 network (no abuse, we were just curious :-) ).

While the RIPE Whois server returned "NL" as the country of that subnet [1],
the "delegated-ripencc-extended-latest" file available at ftp.ripe.net [2] only
contains 51.15.0.0/16, which points to "FR".

Since the first one result contains the correct country code of that IP network,
I would like to ask why "delegated-ripencc-extended-latest" does not include
subnets like this, and where the Whois server fetches his answer from.

Did we miss something? Is there another or a better way of fetching precise
subnet data from RIPE? It would be great if someone could point us into the
right direction. :-)

Thanks, and best regards,
Peter Müller
