About this network

A very early research-network allocation (CSNET-EXT-AS) tied to CSNET, the Computer Science Network, and its Coordination and Information Center.

What it's used for

• Historically, connecting university computer science departments that were not yet on the ARPANET.

Notable

• A single-digit AS number reflects an allocation from the internet's earliest years. CSNET was an early research network, not a commercial ISP, and was run in part out of BBN in Cambridge, Massachusetts.

Interesting

• CSNET was a key stepping stone between the ARPANET and the broader NSFNET-era internet, helping bring academic computing departments online.
