business corporate usa
The AS handle YAMAHA-DEALERS is held by Yamaha Motor Corporation, U.S.A.
What it's used for
- The address space carries internal corporate infrastructure, evidenced by the consistent netname
YMUSNETacross all announced prefixes. - The AS announces 768 IPv4 addresses across 3 prefixes with 2 observed neighbours, a ratio indicative of a small, self-contained corporate estate rather than a transit or access provider.
Notable
- All registrants for the announced prefixes are listed as
YAMAHA MOTOR CORPORATION, U.S.A, matching the AS holder exactly. - The address inventory consists of three /24 blocks (167.174.210.0/24, 167.174.240.0/24, 167.174.246.0/24) that are not contiguous, suggesting site-by-site segmentation or historical allocation patterns.

Internet exchanges
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 2026-11-07, 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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
