AS15306 WALSWORTH-FULTON - WALSWORTH PUBLISHING COMPANY
Unclassified ARIN
Summary
Walsworth Publishing
business media enterprise
The identifiers name a company and the town its plant sits in.
What it's used for
- A printing and publishing company's network. A single IPv4
/24announced from the United States, no IPv6, and two observed BGP neighbours.
Notable
- The AS handle and the netname are identical: the company name joined to a town name.
- Naming the site rather than the function implies other sites, each of which would take its own label, though only this one appears in the routing.
- The registrant is the company in full capitals, a formatting choice that follows the block wherever it is quoted.
- Three addresses were queried for reverse DNS and none returned a name.
- Two upstreams for two hundred and fifty-six addresses.
Interesting
- A netname that names a town is a small disclosure of geography. It says where the equipment is, which a prefix alone would not, and it will keep saying so long after the plant moves.
- Printing yearbooks and journals is a production business, so the network's job is to move large files between customers and presses rather than to serve the public. One block covers that.
- Two upstreams for one small block is redundancy bought for a deadline driven business. A print run that misses its date costs more than a second circuit.

Peering at a glance
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 2026-11-05, 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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
