Syntax
Syntax Description

on
Respond only to DNS requests addressed to the Island.
Defaults
All recursive DNS requests passing through the Island are intercepted by default.
Usage Guidelines
By default, Island intercepts all recursive DNS requests it sees and resolves them locally, even if the request was sent to a different DNS server. This improves DNS lookup speed and allows Island to perform filtering at the DNS level.
In some circumstances, it may not be desirable to intercept DNS requests directed at another DNS server. Enabling the local-only option causes Island to pass these requests on to the targeted server.
Note that Island will never intercept and respond to DNS over HTTPS (DoH) requests targeted to another server. Users wishing to force all DNS reqeusts to be handled by Island may wish to block access to external DoH servers using Island's filtering capabilities. Refer to the Island Router app documentation for more information.
