ABOUTResource Public Key Infrastructure is a specialized public key infrastructure framework to improve security for the Internet's BGP routing infrastructure. RPKI provides a way to connect Internet number resource information (such as ASN and IP addresses) to a trust anchor. Wikipedia ↗︎

All ASN sorted by their number. Sourced from 10 BGP locations.

Upstreams — Any direct adjacent ASN in an AS path sequence that leads to a tier 1 ASN.

ABOUTInternet Exchange Points (IXes or IXPs) are physical places where infrastructure companies interconnect with each other to exchange data destined for their respective networks. These locations are critical for companies to shorten their connection paths to other network participant, this allows for reduced round-trip time and low latency. Wikipedia ↗︎
