Understanding DNS

Think of DNS as a phonebook for the internet. When you type a website name, such as Google, into your browser, your computer uses DNS to convert that name into an IP address, which is used to connect to the website’s server. This process is known as DNS resolution.

There are many DNS servers out there, and your internet service provider (ISP) automatically assigns one to you. However, you can change the DNS server your router uses, which can improve your internet experience in several ways. Want to know more about DNS? Check out this comprehensive guide on DNS.

Reasons to Change Your Router’s DNS

There are several reasons why you might want to change your router’s DNS server:

  1. Speed: Some DNS servers can resolve website names faster than others, resulting in quicker page loading times.
  2. Reliability: If your ISP’s DNS server is frequently down or unreliable, switching to a more reliable server can improve your browsing experience.
  3. Privacy: Some DNS servers offer improved privacy by not logging your browsing history.
  4. Parental controls: Certain DNS servers offer parental control features, allowing you to block access to inappropriate websites.

Before deciding to change your DNS, you might want to test your current DNS server’s speed and reliability. This DNS speed comparison tool can help.
