Changing DNS is the quickest way to boost Internet speed. Previous Mytour articles have guided you on changing DNS settings on Windows 7, 8, and 10. In the following article, Mytour will continue to guide you on changing DNS settings on DD-WRT router.

In addition to changing DNS on your computer, you can also change DNS settings on the router to speed up your Internet. Below, Mytour will guide you on how to change DNS settings on DD-WR router.

Understanding DNS settings on router

When connecting your Router (routing device) to the Internet, it automatically assigns some settings from the Internet Service Provider (ISP) you are using.

Your ISP preconfigures DNS in your router. DNS stands for Domain Name System and is used to translate domain names on the Internet into actual IP addresses. For example, when accessing Google.com, you will connect to an IP address mapped through DNS like the one below:

173.194.33.73

The IP address is automatically mapped when users access any website on the Internet.

Why change DNS settings on your router?

Some Internet Service Providers exploit the DNS system to map to servers they control. Users are completely unaware of this issue because their routers use DNS preconfigured by the ISP.

For example, if your Internet Service Provider (ISP) controls the DNS settings on your router, when you access random websites, these websites do not exist, and you will receive advertisements displayed on your device screen.

By changing the DNS settings on your router to experience faster web browsing on your devices. This is because when a device is connected to your network, the router will automatically transfer the DNS settings to that device. This way, you can protect your entire network system.

Which DNS Server Should You Change To?

There are two DNS servers you can choose from, including: Google Public DNS and OpenDNS. If you're unsure which DNS server to choose, you can switch to using Google Public DNS.

When changing DNS settings in your router, you'll need to enter the primary and secondary settings into the Primary DNS and Secondary DNS fields respectively. Secondary DNS is only used if the Primary DNS is not found.

Below are the DNS addresses for Google Public DNS:

- Primary: 8.8.8.8
- Secondary: 8.8.4.4

The DNS address for OpenDNS is:

208.67.222.222
208.67.220.220
