Summary

Viaduk-Telecom

Ukraine · AI-generated

isp business

A Ukrainian /22 whose AS name says "autonomous system" twice.

What it's used for

  • Internet access. 1,024 addresses in a single /22, four observed BGP neighbours, and no IPv6 announced.

Notable

  • The AS handle reads VIADUK-AS Viaduk-Telecom Autonomous System — the -AS suffix, then the words spelled out.
  • The whole inventory is 212.68.160.0/22, netname VIADUK-TELECOM, with VIADUK DBM as the registered contact.
  • The netname carries no country prefix and no date.

Interesting

  • Saying it twice is what happens when a field meant for a short handle is also the only place a human-readable description will fit. The -AS suffix is convention among people who read routing records; the trailing words are for everyone else.
  • An undated netname with no country code puts this registration among the older ones, before registries needed netnames to sort and stay unique. The convention arrived; this record predates it and nothing has since required it to change.
  • Four neighbours for 1,024 addresses is more redundancy than a network this size needs for its own sake. It usually means the addresses are not what the business sells.

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.
