Summary

Coloplast A/S

Denmark · AI-generated

business medical enterprise denmark

The AS handle COLOPLAST-AS is held by Coloplast A/S.

What it's used for

  • The address space carries internal corporate infrastructure for a medical device manufacturer, evidenced by netnames COLOPLAST and SE-ATOSMED and registrants including Coloplast Network Team and Atos Medical AB.
  • The AS announces 1536 IPv4 addresses across 3 prefixes and 1 IPv6 prefix, with 6 observed neighbours; this low neighbour count relative to the address inventory indicates an internal corporate estate rather than a transit or access network.

Notable

  • Registrants align with the announcer, listing Coloplast Network Team, Coloplast A/S, and Atos Medical AB across the announced blocks.
  • Coloplast acquired Atos Medical, explaining the presence of the SE-ATOSMED netname and Atos Medical AB registrant within the Coloplast AS.
  • The inventory consists of three IPv4 prefixes (193.0.56.0/22, 193.0.60.0/24, 194.0.134.0/24) and one IPv6 prefix (2001:67c:184::/48), all located in Denmark.

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.
