Plesk Recursive DNS Queries | All About

Did you know that the server’s DNS configuration is key to efficient and secure domain name resolution?

Plesk offers a great DNS management system. Furthermore, it offers a way to configure recursive DNS services.

Recursive DNS enables our server to carry out lookup procedures to find the destination IP address for a requesting client. When the DNS server is set to allow recursive service, it carries out queries to find the requested resource’s IP address. This process takes up more server resources, slowing down the server’s performance.

Hence, Recursive DNS enables comes with its share of security risks. This leaves our server vulnerable to denial-of-service attacks. Today, we are going to explore why configuring the recursive DNS service correctly is important.

Additionally, we will also get a quick look at how Plesk can optimize the server’s DNS settings for protection.

How to take control of Recursive DNS with Plesk

We can manage DNS settings and configure recursive DNS by accessing the settings as seen here:

1. First, we have to log into the Plesk Admin Panel.
2. Then, head to DNS Settings under Tools & Settings.
3. Once we click the “Server-wide Settings” tab we will have access to the settings.

Customizing Recursive DNS Settings

We can easily modify recursive domain name service settings according to our needs:

1. Allow Recursive Queries from All Hosts:

   This option lets the server accept recursive queries from any host. Although this offers flexibility, it increases the chances of potential DoS attacks.
2. Allow Recursive Queries from Local Networks Only:

   This setting accepts recursive queries to only your server and hosts within your network. It helps balance performance and security and avoids external threats.
3. Allow Recursive Queries from Your Own Server Only:

   This is the most secure setting. It limits recursive queries to our own server. Additionally, it offers a strong defense against external attacks.
