That's a cool idea and easily implementable.

Hello everyone,
I believe it would be of interest to have system-assigned tags to probes based on whether their network is performing RPKI validation or not. This can be two new tags, “rpki-validating” and “no-rpki-validation”, or similar. The tags should be assigned per probe, using RIPE’s RIS Routing Beacons [1], by running system ping checks every hour / day.

What do you think? Would this be something that you would find useful? 

Thanks,
Antonis
