Iran (Islamic Republic of) · AI-generated

research education iran

The AS handle IRNICAnyCAST-AS is held by Institute for Research in Fundamental Sciences.

What it's used for

  • The address space carries research and academic infrastructure, as indicated by the netname IR-IRNIC and the registrant "Institute for Research in Fundamental Sciences".
  • The AS announces 256 IPv4 addresses across 1 prefix with 2 observed neighbours, a ratio consistent with a small, self-contained institutional network rather than a transit or large access provider.
  • Traffic from this AS consists of research and academic endpoints associated with the Institute for Research in Fundamental Sciences, a non-profit public higher education institution in Tehran.

Notable

  • The RDAP registrant "Institute for Research in Fundamental Sciences" agrees with the registry holder and the AS handle.
  • The address inventory consists of a single /24 block (193.189.123.0/24), indicating a compact and unified allocation for the institution.

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 1,772 prefixes, as published 2026-10-15. 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.
