settings dns

The settings dns command determines the DNS servers the device will use in its own name resolution. The servers here are for the device's own requests; the name resolution of the traffic depends on the settings in the routing table.

Things to Know

• This setting is for the device's own requests. The name resolution of the traffic is determined by the DNS fields in the network namespace record.
• The servers are tried in order. If the first one does not answer, the second is used, and if that one does not answer either, the third is.
• A partial update works. Only the field that is written changes; the others stay as they are.
