Summary
National Weather Service Southern Region Headquarters
government weather nws us
NWS-SOUTHERN-REGION-HEADQUARTERS is operated by the National Weather Service Southern Region Headquarters.
What it's used for
- The address space carries internal government infrastructure, evidenced by the netname
NATIONAL-WEATHER-SERVICE-SRARCHIVEIIREQacross all announced prefixes. - The AS announces 1280 IPv4 addresses across 4 prefixes with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.
Notable
- All registrants match the announcer, consistently identified as National Weather Service Southern Region Headquarters.
- The address inventory consists of four contiguous or near-contiguous blocks within the 216.38.80.0/20 range, reflecting a finely subdivided internal corporate estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, 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 1,779 prefixes, as published 2026-10-23. 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.
