AS paths to this prefix

One real path per vantage point, fanning out from the origin. Where two reach the prefix the same way, those hops are drawn once. Open a path to follow it hop by hop.

Each row is one path genuinely present in the routing table at our last snapshot, read outward from the origin to the vantage point that saw it. Open a row to follow that one path hop by hop. A heavier line in the graph means more vantage points reach the prefix that same way.

What this percentage counts

The denominator counts only full-feed peers — peers carrying a substantially complete routing table at the moment of the snapshot. IXP route-server peers usually feed partial tables and are excluded, because including them would make a normally propagated prefix look as though half the internet could not see it.

It measures how widely an announcement has spread across the networks we can observe. It says nothing about whether the prefix is reachable from any particular place, or how it performs.

No ROA

No ROA covers this prefix, so RPKI has nothing to say about it either way. This is still the common case for a large share of the routing table.

Why these dates start where they do

A first-seen date is the first time we saw that origin, not the first time it appeared in BGP. Our history is forward-only with no backfill, so it says nothing about the period before we started collecting — treat the earliest dates with suspicion.
