cable residential austria

The AS handle WEBSPEED is held by Brandstetter Kabelmedien GmbH.

What it's used for

  • The address space carries customer traffic for a regional cable operator, evidenced by reverse DNS entries pointing to webspeed.at and netnames such as AT-POWERSPEED-CUSTOMER and AT-BRANDSTETTER1-20210428.
  • The network announces 2048 IPv4 addresses across 4 prefixes with only 1 observed neighbour, a ratio that indicates an access network serving local subscribers rather than a transit provider.
  • Traffic from this AS consists of residential broadband users accessing the internet via cable infrastructure in Austria.

Notable

  • Registrants for the largest prefixes are Energie AG Oberoesterreich Services und Digital Solutions GmbH, while the smallest prefix is registered to CEO; Brandstetter Kabelmedien GmbH; Abuse-C Role, indicating a relationship between the cable operator and the regional energy utility.
  • The inventory consists of four distinct IPv4 blocks with no IPv6 prefixes announced.

Reputation

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
