The magic word is "geofeed"! :-)

The format is specified in RFC 8805. Finding and using Geofeed data is
described in RFC 9092.

Example in the wild:

    $ whois -h whois.ripe.net 146.75.0.0 | fgrep geofeed:
    geofeed:        https://ip-geolocation.fastly.com/

Another example below, in this instance the geofeed information is
stored in a 'remarks:' attribute. Unfortunately this particular RIR does
not (yet?) properly support the native RPSL geofeed attribute for IPv6
/48 PI blocks.

    $ whois -h whois.ripe.net 2001:67c:208c::/48 | grep geofeed
    remarks:        Geofeed https://sobornost.net/geofeed.csv

Both approaches work.

Kind regards,

Job
