How-To

L3 Adoption (DNS)

One solution to solve problems when trying to adopt devices is to correctly configure your DNS server.

By default all Unifi Devices try to resolve unifi.localdomain, to find the controller. Even adopted devices, uses this as a fallback.

What you have to do is configure your DNS server, to resolve unifi.localdomain to the IP of your Unifi Controller. So the devices can find the controller.

Tip

Replace localdomain with whatever domain you have on your LAN.

Caution

This will only work if you use the default port (8080), on your Unifi controller
