AS10616 NTIS - National Oceanic and Atmospheric Administration
Unclassified ARIN
Summary
National Oceanic and Atmospheric Administration (NOAA)
government research legacy
The handle says NTIS — the National Technical Information Service — but the registry holder is the National Oceanic and Atmospheric Administration. Both are bureaus of the U.S. Department of Commerce, so this is a handle that outlived its original owner inside the same parent department, not a name that belongs to someone else. Take the holder as the answer: this is a US federal government network.
What it's used for
RIS observes 6 IPv4 prefixes carrying 1,536 addresses — six consecutive /24s out of 204.193.224.0/21 — one IPv6 prefix, 2610:20:1000::/40, and 1 observed BGP neighbour.
That is a single-site federal footprint. Six contiguous /24s announced individually behind one upstream is not an agency-wide backbone; NOAA's larger networks and its research and satellite-data infrastructure live under other ASNs. What sits here is a specific facility or program's public-facing space — servers and services, addressed out of one small legacy /21 and reachable through one provider.
No PTRs came back on the twelve addresses sampled. That is a sample and nothing more; it is not evidence that the reverse zone is undelegated, and no conclusion about the network's posture should be drawn from it.
Notable
Handle-versus-holder mismatches are usually a merger, an acquisition or a rename. In federal space they are more often an internal reassignment: an ASN issued to one bureau in the 1990s gets re-homed to another under the same department, and the registry handle simply never catches up.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 2 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Reputation
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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
