Override IP address space mappings

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/.

This policy does not support dynamic refresh. Changes take effect only after browser restart.

Overrides from the command-line switch --ip-address-space-overrides take precedence over overrides set by this policy.

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
