[RIPE Atlas Ambassadors] Notification for unauthorized access from 176.219.104.1

Hello,

I'm quite surprised that this mailing list showed up in any database as
being responsible in any way for IP addresses.

Clarification on why the IP, and the name of RIPE Atlas may have
appeared on the radar in the first place: RIPE Atlas is constantly doing
"topology measurements" [1], meaning it traceroutes to various targets
over time [2]. If the IP mentioned below appeared in this list, it was
tracerouted to by one or more RIPE Atlas probes.

I believe the best course of action, if you suspect ill behaviour from
that particular IP, is to contact the correct abuse address mentioned by
others in this thread.

Regards,
Robert


[1] see https://atlas.ripe.net/docs/built-in/ measurements 5051, 5151,
6052, 6152
[2] the list contains basically the ".1" of all routed prefixes seen in
BGP. The host name topology4.dyndns.atlas.ripe.net resolves to these IPs
in a round-robin fashion.
