About this network

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.
