Summary

Shazand Petrochemical Company

Iran (Islamic Republic of) · AI-generated

petrochemical corporate iran

The AS handle ARPC is held by Shazand Petrochemical Company.

What it's used for

  • The address space carries corporate infrastructure for a petrochemical facility, as indicated by the netname Shazand-Petrochemical-Company and the registrant Mabna Co. Networks Role.
  • The inventory consists of 256 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, implying a small, isolated internal network rather than a transit or access provider.

Notable

  • The registrant Mabna Co. Networks Role differs from the registry holder ARPC Shazand Petrochemical Company, suggesting the network is managed by a parent or affiliated entity within the Mabna group.
  • The address inventory is minimal, consisting of a single /24 block and a single /48 IPv6 prefix, consistent with a single-site 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: 442 networks and 1,779 prefixes, as published 2026-10-24. 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.
