Abstract
A DNS (Domain Name Server) proxy is configured as a DNS server for clients on the enterprise network to send two or more DNS queries to collect each available IP addresses on a SDWAN member link. IP address collection can be responsive to receiving a DNS request from a client for assigning a FQDN (Fully Qualified Domain Name). Service quality can be evaluated for the service on each member link of the IP addresses. An IP address is assigned to the client based on the service quality evaluation. A notification is transmitted to the client in a DNS response to the IP address request, with the chosen IP address information for configuration.
