how to set dns

How should I set DNS on my RB3011?

When I check in Winbox IP-DNS settings Servers is blank and Dynamic Servers shows 89.101.251.228 and 89.101.251.229. Is this OK?

For just browsing the internet on my laptop this seems sufficient but my unraid server cant find any updates when checking fot them. This wasn’t a problem last week with another router.

That’s fine, dynamic servers in “/ip dns” are dns servers given to you by your ISP. Check IP settings on your unraid server.
