Specifies IP address space overrides for Local Network Access restrictions. This policy allows administrators to treat specific IP address ranges as public (exempt from Local Network Access restrictions) or as local (subject to Local Network Access restrictions). IP address space overrides can be specified using one of the following formats: • [cidr]=[public|local|loopback] where [cidr] is an IP address range in CIDR notation. CIDR overrides apply to all ports. • [ip-address]:[port]=[public|local|loopback] IPv6 addresses must be specified in URL-safe (bracketed) format. For more information about Local Network Access, see https://wicg.github.io/local-network-access/. Example value: 100.64.0.0/10=public [2001:db8::]/32=local 192.168.0.1:8000=public [2001:DB8::8:800:200C:417A]:8080=local

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.
