Should I Use a Local DNS Server?

When it comes to managing your internet connection, one important consideration is whether or not to use a local DNS server. DNS stands for Domain Name System, and it is responsible for translating domain names into IP addresses. In simple terms, it helps your computer find the correct website when you type in a URL.

What is a DNS Server?

A DNS server is like the phonebook of the internet. When you enter a website address into your browser, your computer contacts a DNS server to obtain the corresponding IP address. This IP address allows your computer to connect to the correct web server and load the desired webpage.

By default, most devices use the DNS servers provided by their internet service providers (ISPs). However, there are also public DNS servers available, such as Google Public DNS and Cloudflare’s 1.1.1, that offer alternative options.

The Benefits of Using a Local DNS Server

Faster Browsing:

  • Using a local DNS server can potentially speed up your browsing experience.
  • Local servers cache frequently accessed websites’ IP addresses, reducing the time taken to look up IP addresses for those websites.

Better Security:

  • A local DNS server can provide an additional layer of security by blocking access to malicious websites.
  • You can configure your local server to use blacklists or filters that prevent access to known harmful sites.

Potential Drawbacks of Using a Local DNS Server


  • Setting up and maintaining a local DNS server requires some technical knowledge.
  • You need to ensure that your server is up to date and properly configured to avoid any issues.


  • Some websites may not function correctly when using a local DNS server.
  • This can be due to the way certain websites are designed or if they rely on specific DNS settings for their content delivery networks (CDNs).

How to Set Up a Local DNS Server

If you decide to set up a local DNS server, there are several options available. One popular choice is using software like BIND (Berkeley Internet Name Domain) or Dnsmasq.

Step 1: Install the chosen DNS server software on your preferred operating system.

Step 2: Configure the DNS server with your desired settings, such as blacklists or filters.

Step 3: Point your devices (computers, smartphones, etc.) to use your local DNS server’s IP address instead of the default provided by your ISP. This can usually be done in the network settings of each device.

In Conclusion

A local DNS server can offer faster browsing speeds and enhanced security. However, it requires technical knowledge and may not be compatible with all websites. Consider the potential benefits and drawbacks before deciding whether or not to use a local DNS server for your internet connection.
