Summary

UNHCR Iran

Iran (Islamic Republic of) · AI-generated

government un iran humanitarian

UNHCR-IR-AS is operated by United Nations High Commissioner for Refugees (UNHCR).

What it's used for

  • The address space carries UNHCR's operational network in Iran, as indicated by netnames UNHCR-IR and IR-UNHCR-IRAN-20110105 and registrants UNHCR IRAN ROLE and United Nations High Commissioner for Refugees.
  • The AS announces 2048 IPv4 addresses across 3 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications and data services for UNHCR staff and operations supporting the refugee population in Iran.

Notable

  • Registrants consistently identify the holder as UNHCR Iran, aligning with the AS handle and announced prefixes.
  • The address inventory is compact, comprising three contiguous IPv4 blocks within the 46.255.216.0/22 range.

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 2026-10-23. 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.
