TTL (Time to Live) is one essential aspect of the Domain Name System (DNS) that website owners often overlook. In this article, we’ll explain what Time to Live is, how it affects your website and the best practices for optimizing it. So, without further ado, let’s begin!

What Is TTL in DNS?

TTL, or Time to Live, is a setting in DNS that determines how long a DNS resolver (like your browser or ISP) should cache (store) information about your website’s domain before refreshing it. In simpler terms, it tells DNS servers how long they should remember your domain’s IP address before checking back for updates.

For instance, if you set a Time to Live of 3600 seconds (1 hour), any DNS resolver that looks up your domain’s information will store that data for one hour. After the hour is up, the resolver must query your DNS records again to ensure it has the most up-to-date information.
