Summary

Stiftung Kantonsspital Graubuenden

Switzerland · AI-generated

healthcare business enterprise switzerland

The AS handle KSGR is held by Stiftung Kantonsspital Graubuenden.

What it's used for

  • The address space carries internal hospital infrastructure, evidenced by netnames CH-STIFTUNGKSGR and CH-STIFTUNGKSGR-20260119 registered to the "ICT Security Responsible" of the foundation.
  • The network announces 768 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained enterprise network rather than a transit or access provider.
  • Traffic from this AS consists of internal communications, clinical systems, and administrative endpoints for the Graubünden Cantonal Hospital located in Chur.

Notable

  • Registrants for both announced IPv4 prefixes align with the AS holder, listing "Stiftung Kantonsspital Graubuenden" and its ICT security contact.
  • The address inventory is compact, consisting of a /23 and a /24 block, typical for a single-site corporate or institutional deployment.

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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
