Austria · AI-generated

cable residential austria local

ATKTVPILLERSEE is operated by Kabelfernsehen Pillersee GmbH.

What it's used for

  • The space carries cable television and internet access services, as indicated by the netname AT-KTVPILLERSEE-20120123 and the registrant name "Kabelfernsehen" (cable television).
  • The AS announces 2048 IPv4 addresses in a single /21 prefix (37.61.184.0/21) and one IPv6 prefix (2a06:c500::/29), with 2 observed neighbours. This low neighbour count relative to the address block size indicates a local access network rather than a transit provider.
  • Traffic from this AS consists of residential and local business subscribers in the Pillersee region of Austria, served via the company's cable infrastructure.

Notable

  • The RDAP registrant Kabelfernsehen Pillersee GmbH matches the AS holder and the netname, confirming consistent ownership.
  • The address inventory is compact, consisting of a single contiguous IPv4 block and a single IPv6 prefix, typical of a small regional cable operator.

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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
