Controls which website origins are blocked from making Local Network Access requests to local network endpoints. Network requests initiated from websites that match the specified URL patterns are blocked from issuing Local Network Access requests. For origins not covered by the patterns specified in this policy, the user's personal configuration applies. For detailed information about valid URL patterns, see https://learn.microsoft.com/deployedge/edge-learnmore-ent-policy-url-patterns. For more information about Local Network Access restrictions, see https://wicg.github.io/local-network-access/. Multiple policies can list origins that affect requests to local network endpoints. If an origin matches more than one of the following policies, they take precedence in the following order: - LocalNetworkBlockedForUrls - LocalNetworkAllowedForUrls - LoopbackNetworkBlockedForUrls - LoopbackNetworkAllowedForUrls - LocalNetworkAccessBlockedForUrls - LocalNetworkAccessAllowedForUrls This policy controls access to local network endpoints (private IP addresses) and can be used to block specific websites from accessing local network resources. Example value: http://www.example.com:8080 [*.]example.edu *

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.
