Summary

Huemer Data Center

Austria · AI-generated

hosting datacenter colocation

The AS handle HUEMER- is held by Huemer Data Center GmbH.

What it's used for

  • The address space carries data center infrastructure, evidenced by netnames AT-HDC-20120914 and AT-HDC-20151001 and registrant "Huemer Data Center - Network Operations Center - NOC".
  • The network announces 3072 IPv4 addresses across 2 prefixes with 4 observed neighbours, indicating a hosting or colocation provider rather than a transit carrier.
  • Traffic from this AS consists of hosted servers, colocation racks, and cloud infrastructure located in Vienna, Austria.

Notable

  • Registrants for both announced prefixes agree with the announcer, listing "Huemer Data Center GmbH" and its NOC.
  • The address inventory consists of two distinct IPv4 blocks: 5.254.184.0/21 and 185.119.160.0/22, with no IPv6 prefixes in inventory.

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 1,779 prefixes, as published 2026-10-24. 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.
