Summary

OJSC Naftan

Belarus · AI-generated

industrial corporate belarus oil

ASNAFTAN is operated by Open joint-stock company "Naftan".

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname Naftan and registrant Open joint-stock company "Naftan" for the sole announced prefix.
  • The AS announces 256 IPv4 addresses within a single /24 prefix (185.70.12.0/24) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal operations for the Mozyr Oil Refinery, including industrial control systems, office networks, and corporate data services.

Notable

  • The registrant Open joint-stock company "Naftan" matches the AS holder, confirming direct ownership of the address space.
  • The address inventory is minimal, consisting of a single contiguous /24 block with no IPv6 prefixes announced.
  • OJSC Naftan is a major oil refinery in Belarus; in 2008, the Polimir chemical plant was joined to the company, expanding its industrial footprint.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
