Summary

Skatteforvaltningen

Denmark · AI-generated

government tax denmark internal

SKATTEFORVALTNINGEN is the autonomous system for Skatteforvaltningen, the Danish tax authority.

What it's used for

  • The address space carries internal government infrastructure, evidenced by netnames DK-SKAT-20160512 and SKAT-NET-1 registered to Skatteforvaltningen.
  • The AS announces 1280 IPv4 addresses across 2 prefixes with only 1 observed neighbour, indicating a small, isolated internal network rather than a transit or access provider.

Notable

  • Registrants for both announced prefixes are listed as Skatteforvaltningen, matching the AS holder directly.
  • The address inventory consists of one /22 block (185.151.192.0/22) and one /24 block (195.85.251.0/24), reflecting a modest footprint typical of a single government agency's internal estate.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 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.
