Getting a Domain Name
A domain name is recommended if you wish to access your website without having to remember typing an IP address. In order to get a domain name, you will need to get it from a domain registrar on the internet. Don't worry the process takes less than 5 minutes to complete excluding the time involved in thinking up a good domain name.
For our purposes, we chose the name
astu.pw. Astu is the English rendition of the word अस्तु in Sanskrit which means Amen. Note that the name you choose can be changed at any point in time. You just have to choose the appropriate domain name later on and alter few records as shown later on.
The domain name registrar we have chosen is Google Domains (
https://domains.google.com/m/registrar). There is no logic except for the fact that the payment method does not have to be entered again and again. Please follow the video below to buy a new domain name. After you have selected and made the purchase you have to then point the domain name to the server.
