Permissions-Policy: local-network-access directive

Experimental: This is an experimental technology
Check the Browser compatibility table carefully before using this in production.

The HTTP Permissions-Policy header local-network-access directive controls whether the current document is allowed to make network requests to local and loopback addresses. This policy directive is an alias for the newer local-network and loopback-network directives.

A local address is only accessible on the local network; its target will differ on different networks. For example, 192.168.0.1.
A loopback address is only accessible on the local host; its target will differ on every device. For example, 127.0.0.1, which is generally known as localhost.

Specifically, where a defined policy blocks use of this feature, requests to local and loopback addresses will always fail. If you want more granular control over local and loopback addresses, you should use the newer directives linked above.

See Local Network Access > The local-network-access alias for more details.
