Yes. Go to the Network page under the main menu (≡), make sure that Geek Mode is on, and scroll down to DNS. Tap on the DNS option currently in use to bring up the Edit DNS page, then tap on the down arrow to see a list of other available DNS options.

Yes. Go to the Network page under the main menu (≡) and scroll down to the section titled DNS. Tap on the DNS service to bring up the Edit DNS page. If you wish all DNS requests made by devices to be intercepted and handled by Island (regardless of the DNS server setting on each individual device), check the Always Use Island checkbox. This is not typically needed since Island’s DHCP server will tell devices to use Island for DNS services but may be needed in certain cases.

Yes. On the Network page under the main menu (≡), click on the DDNS field. Enter a unique name to be associated with your Island’s public IP address. This will create a DNS entry for name.myisland.info that maps to your Island’s public IP address.

For Islands with multiple Internet-facing interfaces, the DDNS record will point to one of the active Interfaces. It will be updated automatically if the active interface changes.

If your Internet provider supports IPv4 and IPv6, both IPv4 (“A”) and IPv6 (“AAAA”) DNS records will be created.

There are several advantages: filtering is more precise and Island’s DNS performance is extremely fast. Notably, security and privacy are enhanced because Island essentially provides a DoH gateway for the whole network, including IoT devices that would normally not have access to DoH.

Geek Mode reveals many additional features for advanced users. To enable Geek Mode, go to App settings under the main menu (≡), or tap on the ⋮ icon on any screen where it appears.

To create port-forwards on Island, go to the Network page under the main menu (≡), make sure Geek Mode is on, and scroll down to the Port-forwards section.
