Finding the source of an announcement

[ichnoweb]

Hello,

I am trying to trace how Monocle comes to this finding. When checking the prefix "80.157.130.136/29", I received 398465 as the "origin_asn". When doing it the other way around — checking the ASN — I also see the prefix. But when I try to find the reason for this using monocle rib or monocle search, I do not get any result. Neither RIPEstat nor Hurricane Electric knows this prefix.

So, is there a way to figure out why Monocle is showing me a relation between the ASN and the prefix, or am I just using the monocle search / monocle rib commands incorrectly?

Kind regards,
Christopher

I assume you did a monocle search on this prefix given a time range. Then the 'relationship' you saw was just some origin announced this prefix and received by one of the public BGP collectors.
