Summary
Long Island University
education university legacy
LIUNET is the campus network of Long Island University, a private university in New York State with campuses at Brookville (LIU Post) and Brooklyn.
What it's used for
- Campus connectivity for students, faculty and staff: labs, lecture halls, residence networks, library systems and administrative services.
- It announces a single prefix,
148.4.0.0/16— a full class-B block registered to the university.
Notable
- Institutional education addressing: the hosts behind these IPs are campus machines and university-managed devices, not consumer subscribers.
- Running an entire
/16from one AS is characteristic of a university that received its address space directly in the pre-CIDR era and never had to fragment it.
Interesting
- ARIN's records date this AS number to November 1995, in a sequential run of genuine allocations — an early, and still unchanged, university assignment.

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 1,779 prefixes, as published 2026-10-23. 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.
