It's also connected to the LAN (192.168.0.0/24) by its secondary network interface(192.168.0.1).
It's on this that we are going to install the primary DNS server for our domain (RFC 2606) All the computers on the LAN are automatically assigned a single address by the DHCP service.
The first is dedicated to name resolution, in our case, it is the file db.
The second will be used for reverse name resolution, it is the file db.inv. In this case the name of the primary DNS server "sid." and the email address of technical contact (root.; the @ is replaced by a dot).
It's easy to remember that these two services are running on the same machine whose IP address is 192.168.0.1.
Editing an existing A record and filling in the "update reverse: yes" option doesn't work either. Here we define different log methods for the different categories.The first category is, as its name indicates the default category that is usually assigned to syslog.As a result, it's even possible to associate multiple names to the same machine to update the different available services.For example, pop.example.com, could both point to the primary server where the mail server and the business intranet reside, and the domain could be
