What Should My DNS Server Be on Router?


Angela Bailey

When setting up a router, one of the important settings you need to configure is the DNS server. The DNS server is responsible for translating domain names into IP addresses, allowing your devices to access websites and other online services.

So, what should your DNS server be on your router? Let’s explore some options.

Using Your ISP’s DNS Server

By default, most routers are configured to use your Internet Service Provider’s (ISP) DNS servers. These servers are provided by your ISP and are usually reliable and fast. However, there are some downsides to using your ISP’s DNS server.

  • Pros:
    • Your ISP’s DNS servers are usually well-maintained and optimized for their network.
    • They often provide fast response times, ensuring quick website loading times.
  • Cons:
    • Your ISP can track and log your browsing history using their DNS servers.
    • If your ISP’s DNS servers go down or become unreliable, you may experience internet connectivity issues.
    • In some cases, using your ISP’s DNS servers may result in slow performance when accessing certain websites or online services.

Using Public DNS Servers

If you’re looking for an alternative to your ISP’s DNS servers, you can consider using public DNS servers like Google Public DNS or OpenDNS. These public DNS servers are maintained by reputable organizations and offer certain advantages over using your ISP’s servers.

Google Public DNS

Google Public DNS is a popular choice among internet users. It offers fast response times and a reliable service. To use Google Public DNS on your router, you can set the primary DNS server to 8.8.8 and the secondary DNS server to 8.4.4.


OpenDNS is another widely used public DNS service that provides additional features like content filtering and phishing protection. To use OpenDNS on your router, you need to configure the primary DNS server to and the secondary DNS server to 208.220.220.

The Case for Custom DNS Servers

If you have specific requirements or concerns, you might consider using custom DNS servers.

  • You can set up your own local DNS server if you have advanced technical skills and want complete control over your network’s DNS resolution.
  • You can use specialized DNS servers that focus on privacy, such as Cloudflare’s 1.1.1 or NextDNS.

In conclusion, when it comes to choosing the DNS server for your router, there are several options available depending on your needs and preferences.

Your ISP’s DNS servers: They are usually reliable but may have privacy concerns.

Public DNS servers: Services like Google Public DNS or OpenDNS offer fast performance and additional features.

Custom DNS servers: For advanced users who want complete control or specific privacy features.

Consider these factors when deciding which option is best for you, keeping in mind that changing your router’s default settings may require some technical knowledge or assistance.
