Summary

Tirastel

Germany · AI-generated

business telecom germany

TIRASTEL is operated by Tirastel GmbH.

What it's used for

  • The address space carries corporate and service infrastructure, evidenced by netnames DE-TIRASTEL-20080425, DE-TIRASTEL-20160412, and KartinaTV_Anycast_Network.
  • The AS announces 2,304 IPv4 addresses across 3 prefixes and 3 IPv6 prefixes, with only 1 observed neighbour, indicating a small, self-contained corporate network rather than a transit or large access provider.
  • Traffic from this AS consists of internal corporate operations and specific service endpoints, such as the anycast network for KartinaTV, supporting the company's business in network integration and technical support.

Notable

  • All registrants for the announced prefixes are listed as Tirastel GmbH or Abuse-C Role, consistent with the AS holder.
  • The address inventory is compact, consisting of two /22 blocks and one /24 block in IPv4, alongside three IPv6 prefixes, reflecting a focused corporate estate.

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 1,851 prefixes, as published 2026-11-04. 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.
