Summary
avency
isp hosting business legacy
A German IT services company in the Münster region, selling connectivity and hosting to business customers.
What it's used for
- Business connectivity and hosted services. 24,320 addresses over six prefixes, one IPv6
/32, one observed BGP neighbour.
Notable
- Every netname reads
DE-UNI-X, dated970808and990317— the company's earlier name, still labelling five of the six blocks. - Five of the prefixes are consecutive pieces of
195.60.96.0/19: a/20, a/21, a/22, a/23and a/24, each half the size of the last. - The registry lists "Abteilung Technik" as a contact — the technical department, as a department rather than a person.
- The AS handle holds a street address, Kiebitzpohl 77, in place of a description.
Interesting
- A descending ladder of prefixes out of one range is what happens when a block is handed out a piece at a time and each piece gets announced as it is used. The shape is a record of growth, and it also means the covering
/19is never announced as such — the parts are visible and the whole is not. UNI-Xin five netnames andavencyon the door is the ordinary fate of a rebrand. Address registrations are updated when something forces the issue, and a name in a netname field forces nothing.

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 2026-10-26, 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.
