Summary

Danoffice IT

Denmark · AI-generated

business it-services denmark

DATACON is held by Danoffice IT ApS.

What it's used for

  • The space carries corporate IT infrastructure, evidenced by the netname DK-DANOFFICE-20160824 and registrant Group IT; Danoffice IT ApS.
  • The AS announces 1024 IPv4 addresses within a single prefix (185.165.72.0/22) and observes 1 neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal corporate endpoints and IT services for the organization's business operations.

Notable

  • Registrants align with the announcer, listing Group IT; Danoffice IT ApS and Abuse-C Role.
  • Danoffice IT acquired Datacon Enterprise Solutions A/S, explaining the DATACON AS handle and the integration of the acquired entity's infrastructure.
  • The address inventory is a single contiguous /22 block with no IPv6 prefixes announced.

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: 454 networks and 1,854 prefixes, as published 2026-11-09. 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.
