Summary

Tervisekassa

Estonia · AI-generated

government health corporate estonia

TERVISEKASSA is the autonomous system for Tervisekassa, the Estonian Health Insurance Fund.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by the netname EE-HAIGEKASSA-20160414 and reverse DNS entries pointing to haigekassa.ee.
  • The AS announces 1024 IPv4 addresses within a single /22 prefix (185.147.120.0/22) and maintains only 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of administrative and operational endpoints for the national health insurance authority, including web services and internal systems for managing compulsory social security and health insurance records.

Notable

  • The registrant Tervisekassa aligns with the AS holder, confirming direct ownership of the address space.
  • The organization was formerly known as Eesti Haigekassa and was renamed to Tervisekassa in 2023, a transition reflected in the domain names used in reverse DNS.
  • The inventory consists of a single contiguous IPv4 block with no announced IPv6 prefixes, representing a standard corporate estate for a national government agency.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-29, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
