Autonomous system
AS22512 OPENBSD
Unclassified ARIN
Summary
OpenBSD
software research open-source network
The AS handle OPENBSD is held by OpenBSD, the security-focused Unix-like operating system project.
What it's used for
- The address space carries infrastructure for the OpenBSD project and related software, evidenced by netnames
THEOS-NET-OPENBSD,THEOS-NET-PORTS, andTHEOS-NET-OPENSSH. - The network announces 2048 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with 16 observed neighbours, indicating a small-scale research and development network rather than a transit or access provider.
Notable
- Registrants include Theos Software for the majority of prefixes and Rasselas for two prefixes, reflecting the project's historical and current organizational structure.
- The address inventory is finely subdivided into specific project areas, such as OpenSSH and Ports, consistent with an internal corporate or project estate.

Transit providers
9 upstream, 0 downstream and 14 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 2026-10-16, 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 1,783 prefixes, as published 2026-10-17. 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.
