activitypub_allow_non_public_host

Filters whether a non-public host may be used.

Returning true skips this function's private/reserved-range validation and returns the resolved address as is, for sites that federate over a private network or intranet. A host that does not resolve at all is still rejected.

Note: Callers that fetch through WordPress' safe HTTP APIs (wp_safe_remote_get()/post()) are still subject to core's own loopback/RFC1918 rejection outside its same-host exception. Re-enabling those ranges additionally requires filtering WordPress core (e.g. http_request_reject_unsafe_urls).
