Summary

Islamic Republic of Iran Post

Iran (Islamic Republic of) · AI-generated

postal government iran

The AS handle IRPOST-ESFAHAN is held by Islamic Republic of Iran Post PJSC.

What it's used for

  • The space carries postal network infrastructure, identified by the netname IRPOST and registrant IRAN POST Company NOC.
  • The AS announces 256 IPv4 addresses in a single /24 prefix (178.215.3.0/24) with 1 observed neighbour, indicating a small, isolated internal network rather than a transit or large access provider.
  • Traffic from this AS consists of internal communications and data services for the national postal service's operations in the Esfahan region.

Notable

  • The registrant IRAN POST Company NOC aligns with the AS holder, confirming direct ownership of the address space.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a specific regional office or department within a larger national organization.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
