How Do I Use an External DNS Server?


Angela Bailey

Using an external DNS server can be incredibly useful for managing your website’s domain name system. By utilizing a different DNS server than the one provided by your internet service provider (ISP), you gain more control over your DNS settings and can potentially improve the performance and security of your website.

Why Use an External DNS Server?

There are several reasons why you might want to use an external DNS server:

  • Better Performance: External DNS servers are often optimized to handle a large number of queries, resulting in faster response times for your website visitors.
  • Improved Security: Some external DNS servers offer additional security features, such as protection against distributed denial-of-service (DDoS) attacks or malware.
  • Flexibility and Control: Using an external DNS server allows you to have more control over your domain’s settings, such as managing subdomains or creating custom records.

How to Use an External DNS Server

To use an external DNS server, follow these steps:

Step 1: Choose an External DNS Provider

The first step is to choose a reliable external DNS provider. There are several popular options available, including Google Cloud DNS, Amazon Route 53, Cloudflare, and many more. Research each provider’s features, pricing plans, and reputation before making a decision.

Step 2: Sign Up for an Account

Once you’ve chosen a provider, sign up for an account on their website. This usually involves providing some basic information and creating login credentials.

Step 3: Add Your Domain

Add your domain to the external DNS provider’s dashboard. This typically involves entering your domain name and configuring the necessary DNS records.

Step 4: Update Your Domain’s Nameservers

After adding your domain, the external DNS provider will give you a set of nameservers. These nameservers need to be updated in your domain registrar’s settings. Log in to your domain registrar’s website, locate the DNS settings for your domain, and replace the default nameservers with the ones provided by the external DNS provider.

Step 5: Configure DNS Records

Once the nameserver changes have propagated (this can take some time), you can start configuring your DNS records. This may include setting up A records, CNAME records, MX records, and more, depending on your specific needs.


In summary, using an external DNS server can provide better performance, improved security, and greater flexibility and control over your domain settings. By following these steps to choose an external DNS provider and configure your domain’s settings, you’ll be able to harness the benefits of an external DNS server for your website.
