research legacy

CERN, the European Organization for Nuclear Research, near Geneva, Switzerland,

on one of the internet's early low-numbered ASNs.

What it's used for

  • Networking for the world's largest particle-physics laboratory — the Large Hadron Collider, experiments, and the researchers and data behind them.

Notable

  • A major research institution's own network, not a commercial ISP.
  • The low AS number reflects an early-internet allocation, handed out roughly sequentially in the internet's first years.

Interesting

  • The World Wide Web was invented at CERN by Tim Berners-Lee around 1989-1991.

No IC3 indicators Nothing from the FBI IC3 feed.

Threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
