AS15139 PANASONIC
Unclassified ARIN
Summary
Panasonic Corporation of North America
business enterprise
Six pieces of one range, two of which the registry would not answer for.
What it's used for
- An electronics manufacturer's regional network. Six IPv4 prefixes announced from the United States, no IPv6, and three observed BGP neighbours.
Notable
- All six prefixes come out of
140.212, at three different lengths, with gaps between them that this network does not announce. - Two of the six registry lookups failed, so those blocks' ownership is unknown rather than absent.
- The four that resolved carry the same netname and the same registrant, written entirely in capitals with the corporate form abbreviated, while the holder record spells it out.
- Eighteen addresses were queried for reverse DNS and none returned a name.
- The routing history begins in 2001.
Interesting
- A single netname across every block means the registry records that this company holds space and nothing about how it is used. The routing shows six separate announcements out of one range, which is structure the registry has no field for.
- Abbreviating the corporate form in one field and spelling it out in another is the most common way a company's name fails to match itself. Neither form is canonical and both are current.
- Three upstreams, no IPv6, and nothing in reverse: a regional subsidiary's network built to connect offices and reach suppliers, with no public-facing surface announced from this AS number.

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 2026-10-21, 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 1,779 prefixes, as published 2026-10-22. 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.
