How Does DNS Affect Your Internet Speed?

When you put a URL into your internet browser, your computer doesn’t actually know how to get there. It uses a Domain Name Server (DNS) to look up the numeric IP address to determine how to get to the page you want. In a way, it’s very similar to when people used to use the white pages or call information to find out a person’s phone number. 

If the server you are using becomes slow to respond, simple things like browsing the web become a pain. By default, you are likely using the DNS server of your internet provider. They could force every URL you try to access to display whatever they want, like ad banners around every page. A common example of this is when connecting your phone to Wi-Fi in a store or hotel. You’re often required to agree to terms before you can actually access the internet—that’s because of their DNS!

Use DNS Benchmark To Find a Better Server!

Thankfully, you can change the DNS server that your network uses and speed things up! Obviously, everyone is in a different location, which makes it impossible to say that any one DNS server is best. The best way to determine the best name server to use is DNS Benchmark!

Using the DNS Benchmark tool it's easy to change the dns server on your FlashRouter to attain the best internet speeds available to you.

Their easy-to-use, free program will run a simple test on your internet connection and offer not only the best DNS servers to use but also other tips to enhance your internet connection. Once downloaded, all you have to do is click the “Nameservers” tab and click “Run Benchmark.” When the test is over, you can view their findings in the “Conclusions” tab. 

Use a FlashRouter for Simple Alternate DNS Setup

Lots of routers either hide their DNS settings or don’t let you change them at all! Thankfully, FlashRouters come with DD-WRT firmware which makes it super easy to change! Join the router revolution and unlock the true potential of your network!
