Go to where you purchased the domain name.
They should have a user section to "Manage Domain".
That section should have an area to "Manage DNS".
Change the "name servers" to
ns1.x10hosting.com
ns2.x10hosting.com
I assume you have an x10hosting account.
You have several options.
1. Change the domain of your account to jagoretelangana.com. You do this in the Account Panel
2. If you want to keep the old xxxxxxxxxx.x10hosting.com name, but want jagoretelangana.com to show the exact same content, log onto cPanel and add jagoretelangana.com as a Parked Domain.
3. If you want to keep the old xxxxxxxxxx.x10hosting.com name, but want jagoretelangana.com to show different content, log onto cPanel and add jagoretelangana.com as an Add On Domain. The system will create a subfolder in public_html to hold the site files.
