Summary

Best-Link

Ukraine · AI-generated

isp residential cable ukraine

The AS handle BESTLINK-AS is held by LLC "BEST-LINK".

What it's used for

  • The address space carries residential and small business internet access, evidenced by netnames such as SYNDICATE-NET and SYNDICATE-NET2 registered to FOP Samoilenko Igor Olegovich, and UA-LLCBEST-LINK-20200401 registered to LLC "BEST-LINK".
  • The network announces 3072 IPv4 addresses across 6 prefixes and maintains 8 observed neighbours, a ratio consistent with a regional access provider rather than a transit carrier.
  • As a Cable/DSL/ISP operating in Ukraine, the traffic consists of subscriber eyeballs and local web/API endpoints for residential and small business customers.

Notable

  • Registrants are split between LLC "BEST-LINK" and FOP Samoilenko Igor Olegovich, with the latter holding the larger SYNDICATE-NET blocks.
  • The inventory is composed of six distinct IPv4 prefixes with no IPv6 announcements, reflecting a legacy IPv4-only deployment.

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 1,783 prefixes, as published 2026-10-17. 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.
