Summary

UAS Technikum Wien

Austria · AI-generated

education university vienna

TECHNIKUM-WIEN-AS is operated by UAS Technikum Wien (Fachhochschule Technikum Wien).

What it's used for

  • The space carries institutional infrastructure for the university, evidenced by the netname TECHNIKUM-WIEN and reverse DNS entry sip.technikum-wien.at.
  • The AS announces 256 IPv4 addresses and 1 IPv6 prefix with only 2 observed neighbours, indicating a small, self-contained campus network rather than a transit or large-scale access provider.
  • Traffic consists of internal university services, including VoIP signalling (SIP) and general academic network connectivity for students and staff.

Notable

  • The RDAP registrant Fachhochschule Technikum Wien matches the AS holder and netname, confirming consistent ownership.
  • The address inventory is minimal, consisting of a single /24 IPv4 block and a single /48 IPv6 prefix, typical for a single-site educational institution.

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: 442 networks and 1,778 prefixes, as published 2026-10-20. 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.
