Api Endpoint

netz.halowerk.com

Reports the propagation of a prefix as the fraction of RIS observers that see it, separately for IPv4 and IPv6, because the absolute peer count moves with the size of the measurement network and is not comparable across time or between prefixes. The share is graded against stated thresholds, and — this is the part that makes the number mean something — compared against the other prefixes announced by the same origin AS.
