Summary
Food and Agriculture Organization of the United Nations
government legacy
AS5535 belongs to the Food and Agriculture Organization of the United Nations (FAO), the UN specialized agency for food security, agriculture, forestry, and fisheries. The registry record places it at FAO Headquarters on Viale delle Terme di Caracalla in Rome.
What it's used for
- The organization's own institutional network: staff connectivity and internal systems at the Rome headquarters, plus FAO's public-facing web, statistical, and data services.
- FAO operates worldwide through regional and country offices, and the address space supports the agency's own operations rather than any commercial service.
Notable
- This is an intergovernmental organization network, not a national government or a commercial ISP. The address space is institutional: it exists to run the agency, not to sell connectivity.
- The ASN anchors a legacy
/16, a full Class B-era block, which is a hallmark of an institution that received address space early and has held it ever since.
Interesting
- FAO is one of a small number of UN agencies that run their own autonomous system rather than buying connectivity as an ordinary customer, a reflection of the scale of its data and statistical publishing.

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 1,784 prefixes, as published 2026-10-19. 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.
