Summary

Xellia Pharmaceuticals

Denmark · AI-generated

pharmaceutical corporate denmark

The AS handle XELLIA-AS is held by Xellia Pharmaceuticals ApS.

What it's used for

  • The space carries corporate infrastructure for a pharmaceutical manufacturer, evidenced by the netname DK-XELLIA-20220125 and registrant Xellia Pharmaceuticals ApS.
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix (94.143.227.0/24) and 0 IPv6 prefixes, with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate communications, office workers, and business endpoints for a global leader in fermentation-based non-beta-lactam anti-infectives.

Notable

  • The registrant Xellia Pharmaceuticals ApS agrees with the announcer, confirming the space is owned and operated by the same entity.
  • Xellia Pharmaceuticals was acquired by Novo A/S for US$ 700 million, a transaction that established the current corporate structure for this network.
  • The address inventory is a single contiguous /24 block, typical for a corporate site requiring a modest amount of public IP space for internal services and remote access.

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.
