Autonomous system
AS26660 CLAYCO
Unclassified ARIN
Summary
Clayco
business construction enterprise
CLAYCO is the autonomous system handle for Clayco, Inc.
What it's used for
- The address space is registered to
Cogent Communications, LLCwith the netnameCOGENT-A, indicating the IP block is leased or allocated by Cogent rather than owned by Clayco. - The AS announces a single IPv4 prefix,
38.106.139.0/24, comprising 256 addresses, with no IPv6 prefixes in inventory. - With only 2 observed neighbours in the routing system, the low neighbour count relative to the small address block suggests a limited connectivity footprint, likely for specific site access or internal corporate use rather than broad transit or large-scale residential service.
Notable
- The RDAP registrant for the announced prefix is
Cogent Communications, LLC, which differs from the AS holderClayco, Inc., pointing to a leasing arrangement or historical allocation. - Clayco is a full-service real estate, architecture, engineering, and construction firm, and this AS likely supports its internal network infrastructure or specific project sites.
- The inventory consists of a single /24 block, which is a small, discrete allocation typical of a corporate entity requiring a dedicated address range for its operations.

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 2026-10-19, 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.
