Summary

Stanford University

United States · AI-generated

education research university legacy

An early low-numbered allocation (STANFORD) serving Stanford University in Stanford, California.

What it's used for

  • Campus, research, and administrative networking for Stanford and its schools and labs.

Notable

  • Institutional "eyeball" address space, not commercial hosting.
  • A two-digit AS number places Stanford among the internet's earliest connected institutions.

Interesting

  • Stanford was a hub of early internet development; much of the foundational TCP/ IP work happened in and around the university in the 1970s and 1980s.

Classification and threat

Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 440 networks and 1,773 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
