Unclassified RIPE
Summary
Siemens
business enterprise infrastructure
A netname with underscores, and a registrant that contains the words trading as.
What it's used for
- An industrial conglomerate's network. Eight IPv4 prefixes and two IPv6
/48prefixes announced from Germany, nearly five thousand addresses, through two observed BGP neighbours.
Notable
- Five blocks use a netname of country code, company and allocation date, with dates from the early and mid-nineties, four of them identical.
- One netname is a subsidiary's full name with underscores between the words and ordinary capitalisation, both unusual for this field.
- That subsidiary's registrant runs to a dozen words, naming one company trading as another, with two different corporate forms and an ampersand.
- Another block's netname names a town in a neighbouring country, and a third is a four part code ending in an abbreviation for a group of continents.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Five thousand addresses is a small public footprint for a company of this size, and that is the point: an industrial group's networks are mostly not on the internet at all.
- The trading as clause is a legal restructuring written into a technical database. Somebody had to decide which name belonged in a field with no space for two.
- Allocation dates from the early nineties mark this as address space from before the registry system took its current shape, held continuously ever since.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-26, 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: 445 networks and 1,817 prefixes, as published 2026-10-27. 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.
