education university legacy

LEHIGH is the campus network of Lehigh University in Bethlehem, Pennsylvania.

What it's used for

  • Campus connectivity for teaching, research, administration and student housing. The AS announces a single prefix: Lehigh's legacy 128.180.0.0/16.

Notable

  • A full Class B /16 held by a single university is characteristic of the era when academic institutions were allocated address space directly, long before CIDR and RIR-managed conservation. The ARIN organisation record for Lehigh dates to 1987 and the ASN registration to 1996.
  • Reverse DNS resolves under cc.lehigh.edu, the university's computing-centre domain, confirming institutional rather than commercial use.

Interesting

  • Announcing exactly one prefix and nothing else is the signature of a stable, self-contained institutional network. There is no hosting, no downstream customer space and no address churn here.

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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
