Summary

Region Hovedstaden

Denmark · AI-generated

government healthcare enterprise

The AS handle REGIONH-AS is held by Region Hovedstaden.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames DK-REGIONH, DK-REGIONH-20170706, and DK-REGIONH-20120914 registered to Region Hovedstaden.
  • The inventory consists of 4 IPv4 prefixes totaling 2816 addresses, with 0 IPv6 prefixes announced.
  • With only 1 observed neighbour, the network functions as an isolated internal estate rather than a transit or access provider, consistent with a government agency managing its own IT infrastructure.

Notable

  • All registrants align with the announcer, listing Region Hovedstaden and an Abuse-C Role for all four prefixes.
  • The address inventory is finely subdivided into four distinct blocks, reflecting site-by-site segmentation typical of a large administrative organization.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
