Updating zone files on primary dns facing rejection in dating
This is where we will define a list of clients that we will allow recursive DNS queries from (i.e.
your servers that are in the same datacenter as ns1).
An important part of managing server configuration and infrastructure includes maintaining an easy way to look up network interfaces and IP addresses by name, by setting up a proper Domain Name System (DNS).
DNS zones designate a specific scope for managing and defining DNS records.If you’re not sure which lines to delete, they are marked with a “delete this line” comment above.At the end of the file, add your name server records with the following lines (replace the names with your own).That is, when the DNS receives a name query, “host1.nyc3.example.com” for example, it will look in the forward zone file to resolve host1’s corresponding private IP address.Let’s create the directory where our zone files will reside.
If you are unfamiliar with DNS concepts, it is recommended that you read at least the first three parts of our Introduction to Managing DNS.
