Access the GODADDY WEBSITE and purchase a DNS domain.
In our example, we purchase the domain named MINING-POOL.NINJA.
You can use any website to purchase a DNS domain, GoDaddy is just my personal choice.
Create a DNS entry pointing your website to the computer running Nginx.
In our example, we created a DNS entry pointing the domain MINING-POOL.NINJA to the IP address 188.8.131.52.
Use the NSLOOKUP command to test your DNS configuration
