Autonomous system
AS14872 GZSCI
Unclassified ARIN
Summary
GZ Scientific
business enterprise research
One block, one neighbour, one netname, and every record agrees with every other.
What it's used for
- A company's own network. 4,096 addresses in a single IPv4 prefix, with one observed BGP neighbour and no IPv6 announced.
Notable
69.67.208.0/20carries the netnameGZSCI, registered toGZ Scientific Inc.- The netname is identical to the handle the AS itself is filed under.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- This is the minimum viable autonomous system. One block, filed once, labelled with the same five-letter contraction everywhere, announced to one neighbour, and publishing nothing. Nearly all of the strangeness in this range comes from records touched repeatedly over decades by different people; a record touched once has nowhere to drift.
- Running an AS at all, rather than taking addresses from a provider, means somebody decided the network should be able to change providers without renumbering. That decision is usually made once and then never revisited, which is why so many single-block autonomous systems exist.
- Nothing answering a reverse lookup means nothing here is meant to be reached from outside. The addresses face outward for the company's own traffic.
- A
/20for one company is generous by present standards and unremarkable by the standards of when it was issued.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
