Autonomous system
AS15910 FABASOFT-AT-AS
Unclassified RIPE
Summary
Fabasoft
business hosting enterprise
The only registrant on the block is a role whose name reads like a job title and a road.
What it's used for
- A software company's network. One IPv4
/24announced from Austria, no IPv6, two hundred and fifty-six addresses, across two observed BGP neighbours.
Notable
- The block lists no company at all as registrant, only a role made of three words: two that name the person responsible for a host, and one that names a road.
- The netname is the brand and a country code, and the AS handle is the same two parts with the letters for an autonomous system added on the end, putting the country code in the middle.
- Two hundred and fifty-six addresses is the entire holding, and it has not changed since the routing archive began.
- Two upstreams for one block, which is one more than a network this size needs to function.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Role objects exist so that a network's contacts survive staff turnover: the block points at a role, the role points at whoever currently holds it, and the block never has to be edited. The side effect is a registry full of entries where the responsible party is a phrase rather than a name.
- A software company with its own number and one block is buying independence from its hosting provider. The addresses stay put when the contract changes, which matters when customers have them in firewall rules.

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 2026-10-20, 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 1,779 prefixes, as published 2026-10-21. 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.
