Hosting RIPE
Summary
APA-IT Informations Technologie GmbH
hosting legacy
AS5403 belongs to APA-IT (marketed as APA-Tech), the IT and data-centre arm of APA — Austria Presse Agentur, Austria's national news agency cooperative.
What it's used for
- Hosting, colocation, managed services and container/Kubernetes platforms run out of APA-IT's own Vienna-area data centres.
- The IT infrastructure behind APA's media products, plus outsourcing and hosting for external customers — media houses, publishers and Austrian enterprises.
Notable
- Hosting address space, not consumer address space: IPs here are servers and managed customer systems, so the ASN shows up as origin for a lot of Austrian media and publishing infrastructure.
- APA-IT operates two redundant Austrian data centres, sited on opposite sides of the Danube as part of its resilience story.
Interesting
- A news agency owning a full-blown commercial data-centre business is unusual: APA-IT was carved out of the APA Group's technology operations and now sells hosting to organisations well outside the news trade.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
