Summary

Höhere Technische Bundeslehranstalt Klagenfurt

Austria · AI-generated

education research austria

HTBLA-KLU-AS is operated by Höhere Technische Bundeslehranstalt Klagenfurt.

What it's used for

  • The space carries institutional traffic for a technical federal school, identified by the netname HTL-KLAGENFURT-IP4 and registrant HTL Klagenfurt - Abuse and Hostmaster.
  • The AS announces 256 IPv4 addresses in a single /24 prefix and 1 IPv6 prefix, with 3 observed neighbours, indicating a small, self-contained educational network rather than a transit or large access provider.
  • Traffic consists of student and staff connectivity, academic research, and institutional web services associated with the school's technical and network academy programs.

Notable

  • The RDAP registrant HTL Klagenfurt - Abuse and Hostmaster and the registry holder Hohere technische Bundeslehranstalt Klagenfurt align, confirming the AS is directly owned by the institution.
  • The address inventory is minimal, consisting of one IPv4 /24 and one IPv6 /48, typical for a single-site educational facility.

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.
