Education ARIN
Summary
NYSERNet
education research legacy
An actively routed ASN of NYSERNet (NYSERNET3-AS), the New York State Education and Research Network — a member-owned non-profit that provides high-capacity networking to universities, colleges, and research institutions across New York.
What it's used for
- Regional research-and-education backbone connectivity: linking member campuses to one another, to national research networks such as Internet2, and to commercial transit.
- Announces several thousand legacy IPv4 addresses used by NYSERNet and its member institutions.
Notable
- Institutional, not commercial: the addresses behind this ASN belong to campuses, libraries, medical centres, and research facilities rather than to residential subscribers.
- NYSERNet operates neutral colocation and interconnection facilities in New York City, which makes it a peering point as well as a network.

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 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
