Summary

Donbass Electronic Communications

Ukraine · AI-generated

telecom ukraine business

The AS handle DEC-AS is held by Donbass Electronic Communications Ltd.

What it's used for

  • The address space carries mixed netnames, including DEC-NET for the registrant Donbass Electronic Communications Ltd. and RU-ENERGO-TELECOM-20091210 for ENERGO-TELECOM LLC.
  • The network announces 66304 IPv4 addresses across 3 prefixes and maintains 33 observed neighbours, a ratio that suggests a transit or interconnection role rather than a pure access network.

Notable

  • Registrants differ from the announcer for two of the three prefixes, with ENERGO-TELECOM LLC listed for the largest block 109.254.0.0/16 and the smallest block 84.246.105.0/24.
  • The address inventory is dominated by a single /16 prefix, with the remaining space split between a /23 and a /24.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
