Forwarding BIND DNS Queries to DigitalStakeout PDNS

DNS forwarding is a useful technique for distributing the workload of handling DNS queries across multiple servers and improving the efficiency of the overall system. In this article, we will look at how to configure DNS forwarding on Bind in Ubuntu and CentOS.

Configuring DNS Forwarding on Bind in Ubuntu

First, make sure that you have the Bind DNS server package installed on your Ubuntu system. You can install it by running the following command:
  1. sudo apt-get install bind9
Next, open the Bind configuration file using your preferred text editor. The file is typically located at /etc/bind/named.conf.options.
  1. sudo nano /etc/bind/named.conf.options
Within the file, you will need to add the forwarders option to the options block. This option specifies the IP addresses of the DNS servers that you want to forward queries to. For example:
  1. options {
  2.     forwarders {       
  3.       142.202.107.1;
  4.       142.202.107.2;
  5.     };
  6. };
Save the file and exit the text editor.
Restart the Bind service to apply the changes:
