Autonomous system
AS15106 ASN-LENNOX
Unclassified ARIN
Summary
Lennox International
business enterprise
Eight thousand addresses in one block, and a routing history that starts a decade after the number.
What it's used for
- A manufacturer's network. A single IPv4
/19announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- One prefix carries the whole network. Eight thousand addresses arrive as a single announcement with no more-specifics alongside it.
- The netname is the bare company name and the registrant is the holder, so the address record agrees with itself.
- The AS handle prefixes that name with
ASN-, which is the field's own type written into its value. - The routing history begins in 2012, long after this AS number would have been issued.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- A low AS number with a late first-seen date means the number sat unused, or was used somewhere the collectors never watched, before it started appearing in routing. The number says one thing about age and the routing history says another, and only the second is an observation.
- A single unsplit
/19is the mark of an enterprise rather than a provider. Nobody is being handed pieces of it, so there is nothing to announce separately, and the absence of more-specifics is as informative as their presence would be. - Two upstreams, no IPv6, no reverse names: a network built to reach the outside rather than to be reached from it.

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 2026-10-14, 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 1,771 prefixes, as published 2026-10-15. 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.
