Summary
NOAA Pacific Regional Center
government research noaa us
NOAA-PACIFIC-REGION-CENTER is operated by the National Oceanic and Atmospheric Administration.
What it's used for
- The address space carries government research and administrative functions, evidenced by netnames
NOAA-NWAVEandNOAA-EAST2registered to the National Oceanic and Atmospheric Administration. - The AS announces 2304 IPv4 addresses across 3 prefixes and maintains 3 observed neighbours, a ratio consistent with a small, self-contained government network rather than a transit or large-scale access provider.
Notable
- All RDAP registrants align with the announcer, listing the National Oceanic and Atmospheric Administration for prefixes 137.75.124.0/22, 205.156.56.0/22, and 205.156.60.0/24.
- The address inventory is compact and finely subdivided, reflecting the internal segmentation of a federal agency's Pacific Regional Center facility in Honolulu, Hawaii.

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 2026-10-20, 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.
