Autonomous system
AS3629 NYSERNET-BLK - NYSERNet
Education ARIN
Summary
NYSERNet
education research legacy
One of a block of autonomous system numbers (NYSERNET-BLK) held by NYSERNet, the New York State research and education network.
What it's used for
- Carrying a slice of NYSERNet's
199.109.0.0address space, alongside IPv6. - NYSERNet connects universities, colleges, research institutes, libraries, and schools across New York State to each other and to the wider research internet.
Notable
- Research-and-education space. Addresses under NYSERNet belong to member institutions rather than to consumers or hosting customers.
- NYSERNet holds a run of adjacent AS numbers rather than a single one — see AS3630, its immediate neighbour, registered the same day.
Interesting
- NYSERNet is one of the original NSFNET-era regional networks: the intermediaries that stitched campuses into the early internet before commercial transit existed. Its low AS numbers date from that lineage.

Interconnection

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 2026-11-02, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 449 networks and 1,846 prefixes, as published 2026-11-03. 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.
