Simple DNS question

RouterOS General

Hi.

I have been messing around with my old but trusty rb 433ah Mikrotik, and this came up with the DNS settings under Winbox. Also because a month ago I was
doing configuration on a zyxel usg device.

If you are connected to a ISP with regular broadband, they provide, dynamic IP, dynamic DNS and some other things. And in WinBox it does show these dynamic
DNS servers but you can also enter static DNS servers, like 8.8.8.8 and 8.8.4.4 and they are the public google DNS servers.

So this got me thinking, how do I know what DNS servers mikrotik is using, in the zyxel you could specify the order and make sure the google DNS server
came later in the list and that they are used more as a backup DNS system if the primary fails or goes down for some reason. This does sometimes happen
to dynamic DNS servers that the ISP has access to so having additional DNS servers as backup is a good thing.

Is there any option to tell mikrotik to use the dynamic DNS servers first ?

Or a list that shows the order of use ?

Hmm. Found this.

I guess you could do that, but if the Dynamic DNS does change you will have to fix that. Or keep track of it.

In the DHCP client section of the manual, the

use-peer-dns  (yes | no; Default: yes)

option is documented as follows:

Whether to accept the DNS settings advertised by DHCP Server. (Will override the settings put in the /ip dns submenu.

This seems to indicate that if you are using the ISP provided DNS servers, the DNS servers that you statically assigned are not being used.
