Hello friends,

I want to know that How to change URL..?

What platform are you using to create your website? It depends.

On the Settings -> General screen in a single site installation of WordPress, there are two fields named "WordPress Address (URL)" and "Site Address (URL)". They are important settings, since they control where WordPress is located. These settings control the display of the URL in the admin section of your page, as well as the front end, and are used throughout the WordPress code.

On which platform you have created your website?

A URL is ultimately just a reference that the Domain Name Service uses to figure out what server to connect you to. Once you secure the new URL, all you need to do is update the DNS entries to route traffic to the original IP.
