Summary

NKT Dialog

Ukraine · AI-generated

cable residential ukraine isp

ASZARKO is held by CHP Zarko Alexandr Ivanovich, the legal entity behind the NKT Dialog cable television and internet service provider.

What it's used for

  • The address space carries residential cable TV and internet traffic, evidenced by netnames DIALOG-NET and ZARKO-NET and registrants referencing "CABLE TV NETWORK 'DIALOGUE'" and "Telecompany NKT Dialog".
  • The AS announces 9216 IPv4 addresses across 7 prefixes while maintaining only 3 observed neighbours, a ratio characteristic of an access/eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for cable television and broadband internet services in Ukraine.

Notable

  • Registrants for six of the seven prefixes are "PC TV 'CABLE TV NETWORK 'DIALOGUE'; Telecompany NKT Dialog", while the remaining prefix is registered to "CHP Zarko Alexandr Ivanovich", indicating the AS aggregates space from both the corporate entity and its operating subsidiary.
  • The inventory is dominated by the 176.103.0.0/20 block, with smaller allocations in 176.103.16.0/24, 176.103.17.0/24, 176.103.18.0/23, 176.103.20.0/22, 176.103.24.0/21, and 91.222.76.0/22.

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 1,784 prefixes, as published 2026-10-19. 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.
