Summary

Grünenthal Pharma

Germany · AI-generated

pharmaceutical corporate germany

GRTHL-AS is operated by Grünenthal Pharma GmbH & Co. KG.

What it's used for

  • The address space carries internal corporate infrastructure, identified by the netname GRTHL and registrant Gruenenthal Pharma GmbH & Co. KG.
  • The AS announces 1024 IPv4 addresses within a single prefix (193.28.212.0/22) and maintains 2 observed neighbours, a ratio consistent with a private corporate estate rather than a transit or access provider.
  • Traffic from this network consists of office workers, research and development staff, and internal systems for a pharmaceutical company focused on pain management therapies.

Notable

  • The RDAP registrant Gruenenthal Pharma GmbH & Co. KG matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous /22 block, indicating a finely subdivided internal corporate network without external customer allocation.

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 1,783 prefixes, as published 2026-10-17. 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.
