hosting cloud austria

CLOUDBROKERS-AS is operated by HMB Holding GmbH.

What it's used for

  • The address space carries cloud and hosting infrastructure, evidenced by the netnames AT-HMB-HOLDING-20140424 and AT-STREAMDIVER-20200724 and the registrant Streamdiver GmbH.
  • The AS announces 1280 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a hosting or content delivery role rather than transit.
  • Traffic from this AS consists of web and API endpoints for cloud services, consistent with the operator's business as a European content and cloud provider.

Notable

  • Registrants include HMB Holding GmbH and Streamdiver GmbH, with the latter associated with the AT-STREAMDIVER-20200724 netname.
  • The address inventory is small and subdivided, with one prefix registered to the holding company and another to a subsidiary or related entity.

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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
