ASN AS77 is an Autonomous System Number used to identify a network for BGP internet routing.

Who manages ASN AS77?

AS77 is listed under Johns Hopkins University Applied Physics Laboratory.

What do peers, upstreams, and downstreams mean in ASN data?

Peers are lateral network interconnections, upstreams are transit providers, and downstreams are customer networks receiving connectivity.

What are routes and IP ranges for an ASN?

Routes and IP ranges are the network prefixes announced by the ASN on the internet and show the address space it originates.

Why is WHOIS data shown for an ASN?

WHOIS data provides registration and contact context for ASN ownership, administration, and operational reference.
