Summary

LINZ AG TELEKOM

Austria · AI-generated

isp regional residential business

LINZAG-TELEKOM-AS is operated by LINZ STROM GAS WAERME GmbH fuer Energiedienstleistungen und Telekommunikation.

What it's used for

  • The address space carries a mix of residential and business services, evidenced by netnames such as AT-LINZAG-20040326, AT-LINZAG-20151012, and LI-XSERVAG-20201001.
  • With 38400 IPv4 addresses announced across 10 prefixes and 343 observed neighbours, the ratio suggests a regional access provider with significant peering relationships rather than a pure transit hub.

Notable

  • Registrants largely align with the announcer, including LINZ AG TELEKOM Internet Hostmaster and LINZ AG TELEKOM Internet NOC, though some prefixes are registered to third parties like Hauser GmbH, KEBA Group AG, and Eworx Network & Internet GmbH.
  • The address inventory is finely subdivided, with the largest block being a /17 and the remainder consisting of /22s, /23s, and /24s, indicating site-by-site or customer-specific segmentation.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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 1,783 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.
