Summary
Kolomna-Sviaz TV
isp regional russia
RU-KSTV is operated by CJSC Kolomna-Sviaz TV.
What it's used for
- The address space carries regional internet access traffic, evidenced by reverse DNS entries such as
RU-KSTV-5.42.16-COLOMNA.NETandKSTV-LIR-78.25.144-COLOMNA.NET. - The AS announces 42,240 IPv4 addresses across 5 prefixes and maintains 33 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
- Traffic from this AS consists of subscriber eyeballs and local business connections within the Kolomna area of Moscow Oblast.
Notable
- Registrants for the majority of prefixes are CJSC Kolomna-Sviaz TV, while the 5.42.0.0/18 and 217.196.106.0/24 blocks are registered to Ivan Setevoi of ROST LLC.
- The address inventory is composed of two large /18 blocks and three smaller blocks, all located in the Russian Federation.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
11 upstream, 1 downstream and 12 adjacent networks observed; most-used upstreams first.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,768 prefixes, as published 2026-10-12. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

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.
