Ukraine · AI-generated

isp residential ukraine cable

The AS handle TNS-AS is held by Scientific Production Enterprise "Technaukservice" Ltd.

What it's used for

  • The address space carries residential and business internet access, evidenced by netnames such as Bigline-MAIN, TNSVPS, and UA-TECHNAUKSERVICE-20041111.
  • The AS announces 8960 IPv4 addresses across 16 prefixes and 1 IPv6 prefix, while maintaining 21 observed neighbours. This ratio of address space to peering partners indicates an access or eyeball network rather than a transit provider.

Notable

  • Registrants largely align with the announcer, with multiple prefixes registered to "Scientific Production Enterprise 'Technaukservice' Ltd", though some blocks are held by third parties like Techinform Ltd and LLC "UKRNAMES".
  • The address inventory is fragmented into numerous /22, /23, and /24 blocks, reflecting a collection of acquired or allocated ranges rather than a single contiguous allocation.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 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.

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.
