Enable IPv6 reachability check override
Verified with Microsoft Edge 152.0.4191.53 — updated on July 10, 2026
Supported on: Microsoft Edge version 132, Windows 7 or later
Path in the GPO console
Computer Configuration\Administrative Templates\Microsoft Edge\Network settings User Configuration\Administrative Templates\Microsoft Edge\Network settings Description
This policy enables an override of the IPv6 reachability check. When overridden, the system will always query AAAA records when resolving host names. It applies to all users and interfaces on the device. If you enable this policy, the IPv6 reachability check is overridden. If you disable or don't configure this policy, the IPv6 reachability check won't be overridden. The system only queries AAAA records when it's reachable to a global IPv6 host.

Export Builder
BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
