Summary

Tsentralnaya Gorodskaya Set

Russian Federation · AI-generated

isp regional russia

The AS handle TGS-AS is held by Tsentralnaya Gorodskaya Set (TGS).

What it's used for

  • The address space carries the netname CGNET_NETWORK across all announced prefixes, indicating a centralized network identity for the operator.
  • The AS announces 768 IPv4 addresses across 3 prefixes and maintains 20 observed neighbours, a ratio consistent with a regional access or transit provider.
  • As a regional ISP identified by PeeringDB with the scope "Regional", the traffic consists of subscriber eyeballs and local business connectivity within its service area.

Notable

  • The RDAP registrants for the prefixes are listed as "IMSYS Abuse" and "Abuse-C Role", which differ from the AS holder name but align with the CGNET_NETWORK netname, suggesting a shared administrative or abuse contact structure.
  • The address inventory is compact, consisting of three /24 blocks: 84.23.49.0/24, 91.108.34.0/24, and 91.108.53.0/24.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,843 prefixes, as published 2026-11-01. 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.
