Summary

Sakhalin Energy

Russian Federation · AI-generated

energy corporate oil gas

SEIC-AS is the autonomous system for Sakhalin Energy Limited Liability Company.

What it's used for

  • The space carries corporate infrastructure for the Sakhalin-2 oil and gas project, identified by the netname RU-SAKHALIN2-20131108 and registrant Sakhalin Energy Limited Liability Company.
  • The AS announces 512 IPv4 addresses across 1 prefix (185.40.0.0/23) with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal corporate communications, operational technology, and administrative endpoints for the offshore energy operations in the Sea of Okhotsk.

Notable

  • The registrant Administrative Group of RU.SAKHALIN2 LIR; Sakhalin Energy Limited Liability Company aligns directly with the AS holder.
  • Sakhalin Energy is the operator of the Sakhalin-2 project, a major oil and gas development on Sakhalin Island.
  • The address inventory is a single /23 block, consistent with a dedicated corporate estate for a specific industrial site.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, 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: 447 networks and 1,845 prefixes, as published 2026-10-31. 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.
