Summary

Islamic Republic of Iran Railways

Iran (Islamic Republic of) · AI-generated

railway government iran infrastructure

The AS handle RAI is held by Islamic Republic of Iran Railways.

What it's used for

  • The space carries railway infrastructure traffic, identified by the netname IR-RAI-20170801 and registrant "Railways of Islamic Republic of IRAN".
  • The network announces 1024 IPv4 addresses across 1 prefix (185.215.152.0/22) with 1 observed neighbour, indicating a small, self-contained internal estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate and operational systems for Iran's national railway operator, including signalling, logistics, and administrative endpoints.

Notable

  • The registrant "Railways of Islamic Republic of IRAN" matches the announcer, confirming direct ownership of the address space.
  • The address inventory is a single contiguous /22 block, typical of a dedicated corporate allocation for a specific government entity.
  • The AS was first seen in routing tables in 2017, aligning with the netname date.

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 1,847 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.
