DNS Address Assignment Precedence

Subscriber management supports three methods for assigning addresses to DHCP clients. When multiple methods are configured, the router uses the following precedence to determine which address to assign to the client.

  1. Address defined on the RADIUS server by Internet Assigned Numbers Authority (IANA) vendor ID 4874 attributes 26-4 (Primary-DNS) and 26-5 (Secondary-DNS).
  2. Address defined on the RADIUS server by IANA vendor ID 2636 attributes 26-31 (Primary-DNS) and 26-33 (Secondary-DNS).
  3. Address defined in the local address pool on the router.
