To explain in a simple manner, if you enter in “www.mumbaihosting.com”, in your browser, it will look for the domain’s location online.
It finds the name server information; ns1.mumbaihosting.com & ns2.mumbaihosting.com from the domain database, which further tells the browser what server to access i.e the web server where the website has been hosted.
Once the server is reached, the browser requests information from mumbaihosting.com; the files hosted on the domain name mumbaihosting.com are looked up by the web server software and which then returns the web pages to the browser – and that´s how the website mumbaihosting.com is visible in your browser.
So in order for your web site to be visible online, your domain name has to “point” from the domain database to our servers — that means your domain registration account has to have the correct DNS information in it for our servers.
