Frequently Asked Questions

ASN AS4621 is an Autonomous System Number used to identify a network for BGP internet routing.
AS4621 is listed under Office of Info.Tech. Admin. for Educational Development.
Peers are lateral network interconnections, upstreams are transit providers, and downstreams are customer networks receiving connectivity.
Routes and IP ranges are the network prefixes announced by the ASN on the internet and show the address space it originates.
WHOIS provides registration and contact context for ASN ownership, administration, and operational reference.
This page previews large ASN datasets. Use See more to load additional rows, and upgrade your plan to view complete peer, route, upstream, and downstream data.
