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

No upstream connectivity detected for AS4789 at this time. Next update in ~3 hours.

Downstreams — Any direct adjacent ASN in an AS path sequence that adds one-hop away from a tier 1 ASN.

No downstream connectivity detected for AS4789 at this time. Next update in ~3 hours.

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 ↗︎
