Summary

enterprise business infrastructure
Eight routes tile an entire large range, in every size from /17 down to /24, with one gap.
What it's used for
- A chemical group's technology arm. Ten IPv4 prefixes and one IPv6
/32announced from Germany, sixty-six thousand addresses, through two observed BGP neighbours.
Notable
- Eight of the ten blocks come from one range and descend by exactly one bit each time: a
/17, then a/18,/19,/20,/21,/22,/23and/24, each covering the half the previous one left. - The eight together account for all but one
/24of the range. That one is missing, which is why the total falls two hundred and fifty-six addresses short of a full range. - The remaining two blocks are a
/22and a/24from unrelated space, one of them named for a subsidiary in a different industry. - Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- A descending staircase like this is what happens when a network reclaims its own range piece by piece. Each announcement covers the largest block it can, so the sizes fall by one bit at every step.
- The missing
/24is the interesting part. Something in that range is routed elsewhere or is not routed at all, and it is the only thing preventing a single announcement replacing all eight. - Sixty-six thousand addresses behind two upstreams, with nothing published in reverse, is a network built to reach out rather than to be reached.

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 2026-11-03, 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: 451 networks and 1,853 prefixes, as published 2026-11-04. 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.
