Summary

Norsk Helsenett SF

Norway · AI-generated

health government infrastructure vpn

NORWEGIANHEALTHNETWORK is operated by Norsk Helsenett SF.

What it's used for

  • The address space carries infrastructure for the Norwegian health sector, with netnames NO-NHN-20031216, NO-NHN-20061108, NO-NHN-20110309, and NO-NHN-20150114 all registered to Norsk Helsenett SF.
  • The AS announces 27,648 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, maintaining 7 observed neighbours; this ratio indicates a specialized access network rather than a transit provider.
  • Traffic consists of secure ICT infrastructure supporting electronic interaction between hospitals, municipalities, and other participants in the Norwegian health and care services.

Notable

  • Registrants for all announced prefixes consistently identify Norsk Helsenett SF or its IRT-NHN handle, aligning perfectly with the AS holder.
  • Norsk Helsenett SF is a state enterprise under the Ministry of Health and Care Services, founded on 1 July 2009 to ensure secure infrastructure for the national health system.
  • The inventory comprises four distinct IPv4 blocks and a single IPv6 prefix, reflecting a segmented internal corporate estate for site-specific health network connections.

Classification and threat

Residential Fixed-line consumer ISP. Addresses here are homes.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
