Summary

DK Svyaz OOO

Russian Federation · AI-generated

business russia telecom

DKTEL-OPRF is operated by DK Svyaz OOO.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname SPARKTELL and reverse DNS entries pointing to sptell.net.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (79.137.249.0/24) and maintains only 1 observed neighbour, indicating a small, self-contained business network rather than a transit or large-scale access provider.
  • Traffic from this AS consists of internal corporate endpoints and services for DK Svyaz OOO, a Russian telecommunications operator.

Notable

  • The RDAP registrant for the announced prefix is Spark Tell NOC; Abuse-C Role with netname SPARKTELL, which differs from the AS holder name DK Svyaz OOO, suggesting a specific operational unit or subsidiary managing the IP space.
  • The inventory is compact, consisting of a single contiguous /24 block with no IPv6 prefixes announced.

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.
