The switch will hijack DNS requests for the configured domain and return
the IP addresses configured using the ip dns server address command.
Installing a root certificate on the switch for the domain where the CNAME
matches the domain parameter may avoid errors during redirection.
Example
console(config)#ip dns domain-list fqdn.dell.com
console(config)#ip dns server address 192.168.1.4 192168.1.5
