What Is a DNS?

Before you attempt to change the DNS, you should know what it is and how it can make a difference. The DNS (Domain Name System) is the single most revolutionary tool that changed the internet forever. To understand what your Xfinity modem router DNS does, you need to first understand what an IP address is.

So, every website you visit has an IP address that is responsible for taking you to the destination. An IP address is a combination of numbers separated by periods. For instance, Amazon has millions of IPv4 addresses. Before there was a DNS system, you had to know these numbers to get to the website.

Now, all you need is the domain name and you can access your website. So, if you type in in the address bar, it will take you to the website. You can use any Xfinity modem router combo as this is universal for all internet connections. This is very convenient as it would’ve been impossible to memorize IPv4 addresses to the hundreds of websites you may use every day.

Similarly, your router also has a DNS server and an IP address. You need to know the IP address and your Xfinity router login to get to the admin panel. Here, you can change the router settings, update your firmware, and update security protocols or QoS
