Summary

Ontario Health

Canada · AI-generated

government health enterprise

SSHA-DC-ASN is held by Ontario Health, the provincial agency overseeing healthcare administration in Ontario.

What it's used for

  • The address space carries internal government and healthcare infrastructure, evidenced by netnames SSHA-ONE-NETWORK and ONT-GOV4, and reverse DNS entries like dwp.ehealthontario.on.ca and gwb04-ppe.gw.one-mail.on.ca.
  • The AS announces 2048 IPv4 addresses across 7 prefixes with only 1 observed neighbour, indicating a small, self-contained internal corporate estate rather than a transit or access network.

Notable

  • Registrants for the majority of prefixes are listed as Ontario Health; OH NOC; OHCSO, while the 138.218.196.0/24 prefix is registered to GONET, reflecting the broader Government of Ontario network infrastructure.
  • The address inventory is finely subdivided into /24s and a /23, consistent with site-by-site segmentation for a large administrative body.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-07, 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: 454 networks and 1,852 prefixes, as published 2026-11-08. 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.
