Autonomous system
AS3630 NYSERNET-BLK - NYSERNet
Education ARIN Educational/Research
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
- Announcing small pieces of NYSERNet's
199.109.0.0address space, plus IPv6. - NYSERNet provides connectivity and shared services to New York's universities, colleges, research institutions, libraries, and school districts.
Notable
- Institutional research-and-education space, not eyeball or hosting space.
- Sits directly beside AS3629, another NYSERNet number from the same registered block. Regional research networks commonly hold several ASNs and hand them out to member sites or use them for distinct routing roles.
Interesting
- NYSERNet traces back to the NSFNET regional network era, when state and regional networks were the connective tissue of the early internet — which is why its numbers sit this low.

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: 454 networks and 1,849 prefixes, as published 2026-11-14. 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.
