Summary

Põhja-Eesti Regionaalhaigla

Estonia · AI-generated

healthcare hospital business

The AS handle PERH is held by Sihtasutus Põhja-Eesti Regionaalhaigla.

What it's used for

  • The address space carries hospital infrastructure, evidenced by the netname EE-PERH and the registrant SIHTASUTUS EESTI TERVISHOIU PILDIPANK (Estonian Healthcare Image Bank) with administrator pacs.ee.
  • The network announces 256 IPv4 addresses across 1 prefix and maintains 2 observed neighbours, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal hospital systems, specifically medical imaging and PACS (Picture Archiving and Communication System) endpoints for the regional hospital.

Notable

  • The RDAP registrant for the announced prefix is SIHTASUTUS EESTI TERVISHOIU PILDIPANK, which differs from the AS holder Sihtasutus Põhja-Eesti Regionaalhaigla, reflecting the specific department or foundation managing the image bank infrastructure within the hospital's network.
  • The inventory consists of a single /24 block (185.50.99.0/24) with no IPv6 prefixes announced.

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.
