Summary

Anexia Cloud Solutions GmbH

Austria · AI-generated

hosting cloud austria

EMERION-AS is operated by Anexia Cloud Solutions GmbH.

What it's used for

  • The address space carries hosting and cloud infrastructure, evidenced by netnames AT-ANEXIA-20120416 and EMERION-SERVERLAN-3.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small-scale hosting or edge network rather than a transit provider.
  • Traffic consists of web and API endpoints for Anexia's cloud and hosting services, including infrastructure previously operated by emerion.

Notable

  • Registrants align with the announcer, listing Anexia Cloud Solutions GmbH and EMERION Hostmaster.
  • Anexia acquired emerion, an Austrian mass hosting provider, integrating its infrastructure into the Anexia portfolio.
  • The inventory consists of two contiguous IPv4 blocks in Austria with no announced IPv6 prefixes.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
