Unclassified ARIN
Summary
Green Shield Canada
business corporate canada
GREENSHIELD is the autonomous system for Green Shield Canada, a not-for-profit health benefits carrier.
What it's used for
- The address space is registered under the netnames
GREENSHIELDandGREEN-SHIELD, both attributed to Green Shield Canada, indicating an internal corporate estate rather than a public access network. - The AS announces 1280 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a private business network with limited external peering.
Notable
- Registrants for both announced prefixes align with the AS holder, Green Shield Canada.
- The inventory consists of two distinct IPv4 blocks: 199.71.240.0/22 and 199.71.147.0/24, with no IPv6 prefixes in inventory.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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: 442 networks and 1,771 prefixes, as published 2026-10-15. 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.
