Summary
Brooklyn Law School
education university legacy
BROOK-LAW is the campus network of Brooklyn Law School, an independent law school at 250 Joralemon Street in Brooklyn, New York. ARIN records the AS to the school itself, with school staff as the technical and administrative contacts.
What it's used for
This is a small, self-contained campus network rather than a service provider. RIS sees just 2 IPv4 prefixes totalling 768 addresses and no IPv6, announced through only 2 observed neighbours — the profile of a single-site institution buying transit from a couple of upstreams, not of anything that resells connectivity. Both announced prefixes, a /23 and a /24, are registered in ARIN directly to Brooklyn Law School under its own BLS network handles, so the routed inventory and the legal holder agree completely. There is no third-party or broker-registered space anywhere in the announcement, which is the main thing worth checking in this AS range.
The space is what you would expect a law school to route: outward-facing institutional services, library and research resources, and campus connectivity for faculty, staff and students at a school whose academic building and residence hall sit within a few blocks of each other in Downtown Brooklyn.
Notable
Brooklyn Law School is a standalone institution — it is not part of Brooklyn College or the City University of New York, despite the name, and it operates its own IT and network estate accordingly. The ASN itself is an ARIN allocation from 2007 rather than an early-internet assignment; a low AS number in this range says nothing about age.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-24, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 2026-10-24. 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.
