Summary

Atea

Denmark · AI-generated

business enterprise it denmark

ASN-ATEA- is operated by Atea A/S.

What it's used for

  • The address space carries corporate IT infrastructure, evidenced by netnames such as DK-ATEA-AOS3 and DK-ATEA-AOS4 and registrant details citing the "Network Core Infrastructure team".
  • With 19,712 IPv4 addresses announced across 21 prefixes and only 1 observed neighbour, the ratio indicates an internal corporate estate rather than a transit or access network.

Notable

  • Registrants are consistent with the announcer, with most prefixes registered to "ATEA A/S - Network Core Infrastructure team & RIPE Maintainer", though one prefix (178.20.216.0/23) is registered to "Fionia IT ApS".
  • The inventory is finely subdivided into multiple /22, /23, and /24 blocks, reflecting site-by-site segmentation typical of a large enterprise IT provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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 1,782 prefixes, as published 2026-10-16. 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.
