Summary

The company's registered name begins with a lower case letter, and everything else still names the old one.
What it's used for
- An information technology services company. Five IPv4 prefixes and one IPv6
/32announced from Germany, eleven thousand addresses, across three observed BGP neighbours.
Notable
- The holder's name is written in lower case before its two corporate forms, which is how the company registered it rather than a transcription error.
- The AS handle and all five netnames carry a completely different, older brand.
- Four of the blocks form a rising run from a
/21through a/22to two/24prefixes, and that run stops two/24blocks short of meeting the/19above it. - Every block shares one netname and one pair of registrants, with no variation.
- Fifteen addresses were queried for reverse DNS and none returned a name.
Interesting
- The gap between the run and the
/19is the interesting part. Two/24blocks sit between them that this network does not announce, and closing that gap would let four routes collapse into one. - A retired brand surviving in the AS handle and in every netname, while the holder field carries the current name, is the usual pattern: the name people see gets updated and the identifiers do not.
- Eleven thousand addresses with nothing published in reverse says this network is a place work happens from rather than a service anyone connects to.

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 1,772 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.
