Find Your Perfect Domain and Register It Before Someone Else Does!
To put it simply a domain name registrar is a service that lets you register and purchase domain names.

A domain is a user-friendly naming system that allows people to easily navigate web servers and web pages. Rather than making people type in an IP address whenever they want to access a certain web page (like 38.97.225.253), websites are instead assigned easy-to-remember character strings, called domains.
A domain name is the foundation of your website. It’s how your website visitors navigate to your site, and it plays a role in how people discover you online. It’s often the first impression that potential visitors get of you and your website as well—so registering the best domain name possible is important.
