It looks for the authoritative DNS servers, or it looks elsewhere.Here’s a quick step by step process of how it works once you type in the domain name you want to visit: Because it takes seconds for the news to spread, everyone knows the server is down. If the DNS server is unavailable, the browser cannot get the website’s IP address and returns an error. Unfortunately, end users are unaware of the necessary background processes to keep the system running. When the DNS server delivers the IP address, the browser connects to the webpage, which shows on your screen. When a website’s name is put into the browser, it queries the nearest DNS server for its IP address. A DNS server’s job is to tie the name to the number. Numbers or IP addresses are associated with that domain name and indicate the location of the website on the internet. The name is what people type into a browser to access a site, such as our website. For example, a number has a name and a number attached to it. Understanding how DNS servers work might help troubleshoot when you have DNS problems.

Today, I’ll share more details on DNS testing and how you can run your DNS response time test to see if you can improve the performance of your DNS and website’s speed. Since Google’s research indicates your website’s bounce rate can increase by 32% if it loads between one and three seconds, it’s essential to shave off as much time as possible from page load speeds. Without it, users would need to remember the long string of numbers of your IP to visit your website instead of a user-friendly address. When it comes to decreasing your website’s load times, your DNS and how quickly it responds are often overlooked.
