Unclassified ARIN
Summary
National Oceanic and Atmospheric Administration (NOAA)
government research legacy
NOAA-NWAVE is N-Wave, the national science network of the US National Oceanic and Atmospheric Administration — the federal agency behind the National Weather Service, ocean and fisheries science, and satellite environmental observation.
What it's used for
- NOAA's agency-wide backbone: a NOAA-owned and operated shared network connecting field sites, campuses, data centers, and supercomputing facilities across the country, including Alaska and Hawaii.
- Moving the large scientific datasets NOAA's mission runs on — weather models, satellite downlinks, and ocean and climate observation data.
Notable
- A government research network, not a commercial ISP. Its several hundred thousand IPv4 addresses serve NOAA's own facilities and partners rather than paying subscribers.
- N-Wave has been in operation since 2009 and is built on partnerships with the academic and state research-network communities.
Interesting
- The ASN itself long predates the N-Wave brand: ARIN's record goes back to 1994, so the number carries NOAA's early-internet allocation forward into the agency's modern science backbone.
- The backbone was upgraded to 100 Gbps in 2019 and to 400 Gbps in 2022, which is the scale that near-real-time weather and climate modeling demands.

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 2026-10-20, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
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 1,778 prefixes, as published 2026-10-20. 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.
