JSC Oil Processing Company

Russian Federation · AI-generated

business oil corporate russia

ASTPK is the autonomous system for JSC Oil Processing Company.

What it's used for

  • The space carries corporate infrastructure for an oil processing entity, identified by the netname OILPC-NET and registrant OILPC NOC TEAM; JSC Oil Processing Company.
  • The AS announces 512 IPv4 addresses within a single prefix (192.146.140.0/23) and maintains 5 observed neighbours, indicating a small internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate communications and systems for the oil processing division, distinct from consumer or public internet services.

Notable

  • The registrant OILPC NOC TEAM; JSC Oil Processing Company aligns directly with the AS holder ASTPK JSC Oil Processing Company.
  • JSC Oil Processing Company is a subsidiary of Lukoil, formed from the merger of Langepasneftegaz, Uraineftegaz, and Kogalymneftegaz.
  • The address inventory is compact, consisting of a single /23 block with no announced IPv6 prefixes.

Reputation

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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
