government health un switzerland
The AS handle WHO-AS is held by the World Health Organization.
What it's used for
- The address space carries internal organizational infrastructure, evidenced by netnames
WHOandWHO2associated with the United Nations agency. - The inventory consists of 65,792 IPv4 addresses across 2 prefixes, with 0 IPv6 prefixes announced.
- With only 2 observed neighbours, the low neighbour count relative to the address block size indicates a closed, internal corporate estate rather than a transit or access network.
Notable
- Registrants align with the announcer, with the /24 prefix explicitly registered to the World Health Organization (WHO) and the /16 prefix carrying the netname
WHO. - The address inventory is composed of one large /16 block (158.232.0.0/16) and one smaller /24 block (195.190.29.0/24), both located in Switzerland.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,773 prefixes, as published 2026-10-13. 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.
