government enterprise infrastructure
Eighteen neighbours for fifteen hundred addresses, and the umbrella body holds one block while its own IT company holds the other two.
What it's used for
- A social insurance umbrella organisation's network. Three IPv4 prefixes and one IPv6 block announced from Austria, one thousand five hundred and thirty-six addresses, across eighteen observed BGP neighbours.
Notable
- The holder name is a single compound word for the carriers plus their association, written with vowel pairs standing in for the accented letters the registry cannot store.
- Two blocks carry a netname built from the initials of an IT services company owned inside the same structure, and are registered to that company. The third carries the umbrella body's own netname and registrant.
- The AS handle matches the third netname, so the number is filed under the parent while most of the address space is filed under the subsidiary.
- Every block lists a role contact for abuse and no individual.
- Nine addresses were queried for reverse DNS and none returned a name.
Interesting
- Eighteen upstreams is a great deal of redundancy for a network this size. Claims processing for a country's health and pension carriers cannot pause while somebody's fibre is repaired, and the connection count reflects that rather than any traffic volume.
- Public bodies that spin their computing into a separate company end up split across registry records exactly this way: the mandate stays with the parent, the machines move to the subsidiary, and the address space follows the machines.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
