Summary

DKM Ltd

Ukraine · AI-generated

isp ukraine small

ALBA-ISP is the AS handle for DKM Ltd, a Ukrainian internet service provider.

What it's used for

  • The address space carries residential or small-business access traffic, indicated by the reverse DNS record 254-14.alba.dp.ua which points to the Dnipropetrovsk region.
  • The network announces a single IPv4 prefix, 193.151.12.0/22, comprising 1024 addresses, with no IPv6 prefixes in inventory.
  • With only one observed neighbour in the routing system, the low neighbour-to-address ratio suggests a local access network rather than a transit provider.

Notable

  • The RDAP registrant for the announced prefix is DKM Ltd, which aligns with the registry holder and the AS name ALBA-ISP.
  • The address inventory consists of a single contiguous /22 block, representing a compact and focused allocation for a regional operator.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
