You can define primary servers if the zone is a secondary and then provide an email address/username of the user who manages the domain.Here, you also configure TTL for the domain, domain record expiry, retry intervals for the domain, etc.You also have more more granular controls for each domain.In the DNS Manager, right-click on your new domain and then click on Properties.
I also like to restart my DNS again after all that fun stuff.Root hints are the root DNS servers that sit atop the DNS pyramid scheme.I’ve only ever needed to edit these once, at the instruction of Microsoft during a support call for an environment that was in a walled garden. Here, you can decrease logging so that the server only logs errors, warnings or even nothing at all. This is like a special rockin’ tcpdump for DNS logs.The Enable BIND secondaries allows a Mac to act as a secondary DNS server for the records stored on this server.This doesn’t work too well with Active Directory service records, in my experience, but works pretty well with anything else provided you define each zone to cache. If you need to edit these then you might be doing something wrong.
