Summary

National Iranian Oil Company

Iran (Islamic Republic of) · AI-generated

government oil energy corporate

The AS handle NIOC-AS is held by National Iranian Oil Company.

What it's used for

  • The address space carries corporate infrastructure for a state-owned oil and gas producer, as indicated by the netname IR-NIOC-20040326 and registrant "National Iranian Oil Company".
  • The AS announces 4096 IPv4 addresses across 1 prefix (217.174.16.0/20) with 1 observed neighbour, implying a small, self-contained internal network rather than a transit or access provider.

Notable

  • The registrant "National Iranian Oil Company" matches the AS holder name exactly.
  • The National Iranian Oil Company is a government-owned entity responsible for Iran's crude oil and gas exploration, production, and distribution.
  • The inventory consists of a single /20 block, representing a finely subdivided internal corporate estate.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
