Ukraine · AI-generated

isp residential ukraine access

TKS-AS is operated by Sumski Telecom Systems Ltd.

What it's used for

  • The address space carries residential and mobile access traffic, evidenced by reverse DNS entries such as pppoe-static-93-0.tks.sumy.ua, lctgora-254.clients.tks.sumy.ua, and i0.vpdn4.tks.sumy.ua.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and maintains 21 observed neighbours, a ratio consistent with a regional access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs in the Sumy region of Ukraine, utilizing PPPoE and VPDN technologies for last-mile connectivity.

Notable

  • Registrants for both announced prefixes (SUMY-TELECOMSYS-NET and TKSYS-NET) align with the AS holder, listing Sumski Telecom Systems Ltd and its coordination center.
  • The inventory consists of two /22 blocks, one in the 95.47.0.0/16 range and one in 193.34.0.0/16, 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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
