Summary

Teledyne Systems Limited

Russian Federation · AI-generated

business corporate russia teledyne

The AS handle TELEDYNE-AS is held by Teledyne Systems Limited.

What it's used for

  • The address space carries corporate infrastructure, evidenced by reverse DNS records pointing to sub.tsl.ru and netnames such as TSL-NET and RU-TSL-20110127.
  • The AS announces 22,016 IPv4 addresses across 18 prefixes with 5 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate endpoints and office workers for Teledyne Systems Limited, a Russian entity distinct from the US-based Teledyne Technologies.

Notable

  • Registrants align with the announcer, listing LLC Teledyne Systems Limited and Abuse contact for the majority of prefixes.
  • The address inventory is finely subdivided into multiple /22 and /24 blocks, reflecting site-by-site segmentation typical of a large corporate network.
  • The operator is a Russian limited liability company, not to be confused with the US multinational Teledyne Technologies or the Indian Teledyne Systems Limited.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
