DNS server order?

“/ip dns print” shows servers and dynamic servers but does not indicate which servers are primary and which are secondary. i would like to use my ISP-designated dynamic servers as primary servers and then add a few public domain servers as secondary servers.

the wiki docs do not say anything about DNS server order. does anyone know how DNS servers are ordered? What are the commands to specify DNS server ordering?

1 I would write down your isp dns server address.
2 Then disable use peer dns in the DHCP client.
3 Goto IP DNS and put the servers you want to use in manually. (They will be used in that order) (I use google 8.8.8.8 and 8.8.4.4)
4 Make sure your dhcp server assigns your network the routers address for dns
