Unclassified RIPE
Summary
Xenologics
isp business
An AS whose name field says what it is rather than who it is: Internet-Service-Provider.
What it's used for
- Internet access in Germany. 8,192 addresses in a single IPv4 prefix, one IPv6 prefix, and three observed BGP neighbours.
Notable
- The AS handle is the generic string
Internet-Service-Provider. - The whole IPv4 inventory is
212.44.160.0/19, netnameDE-XNCNET-990325. - The IPv6 announcement is
2a00:1978::/32. - The registry entry carries the short handle
XNCalongside the full company name, Xenologics Networks & Communications GmbH. - Three sampled addresses were queried and none returned a reverse name.
Interesting
- Every other entry in a routing table's name column is a company, a brand or an acronym. This one is a job description. Somebody filling in the form read the field as asking what the network does, and nobody has corrected it in the quarter century since, because nothing downstream of BGP reads that field for meaning.
- The netname takes the opposite approach and compresses the three-word company name to four letters. The same organisation described itself in the most generic and the most cryptic terms available, in two fields of the same registry.
- A
/19with three upstreams, where none of the sampled addresses answered with a name, is a provider that sells connectivity rather than hosting. The addresses go out to customers, and naming them is the customer's problem.

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.
