AS15492 PFALZWERKE-AS Kurfuerstenstrasse 29
Unclassified APNIC
Summary
Pfalzwerke
business enterprise infrastructure
The AS handle carries a street address and a house number.
What it's used for
- A regional utility company's network. A single IPv4
/24announced from Germany, no IPv6, two hundred and fifty-six addresses, through two observed BGP neighbours.
Notable
- The AS handle is the company code followed by a street name and a number, which is postal information in a field meant for a network identifier.
- The one block lists three registrants: the company, an abuse role, and a role account belonging to a differently named organisation.
- The netname is the company name and the country code, with nothing else.
- Three addresses were queried for reverse DNS and none returned a name.
- Two hundred and fifty-six addresses, announced whole, unchanged in shape since the network first appeared.
Interesting
- A street address in an AS handle is a copy-and-paste artefact from a paper form, preserved because nothing in the system objects to it and nobody has needed to change it since.
- The third registrant, a role account under another name, is the tell that the network is run by somebody else. Utilities buy their connectivity and their operations, and the record shows who.
- The smallest routable block with two upstreams is what a company buys when it needs to stay reachable rather than to serve traffic. Reliability, not capacity.

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 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
