Summary

National eHealth Operator CJSC

Armenia · AI-generated

government healthcare infrastructure

E-HEALTH is the autonomous system for National eHealth Operator CJSC.

What it's used for

  • The space carries the national electronic healthcare system, as indicated by the netname EHEALTH and registrant National Ehealth Operator CJSC.
  • The AS announces 256 IPv4 addresses within a single prefix (91.217.157.0/24) and maintains 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS consists of backend infrastructure for the unified state information system that stores population health data, managed on a concession basis by the operator.

Notable

  • Registrants National Ehealth Operator CJSC and National Electronic Healthcare Operator CJSC align with the AS handle E-HEALTH.
  • The address inventory is a single /24 block, consistent with a dedicated corporate or government estate rather than a subdivided multi-site network.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
