Summary
New Jersey Institute of Technology
education university research legacy
Autonomous System 4246 (NJIT-AS) belongs to the New Jersey Institute of Technology, a public research university in Newark, New Jersey.
What it's used for
- Campus network connectivity: faculty, staff, student residences, labs, and the university's public web and research services.
Notable
- University address space, which behaves unlike consumer space. A single IP can be a lecture hall, a dorm room, or a research cluster, and NAT means many people can share one address.
- NJIT holds a full legacy
/16, a generous allocation typical of universities that connected in the early days of the internet. - The AS number is from the mid-1990s and has been held by the university ever since. The
-Zsuffix on the ARIN org handle is a registry housekeeping artifact, not a sign the number changed hands.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-21, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Education University, school or national research and education network.
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 2026-10-22. 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.
