This article will explain exactly how to point your domain name to a paid VPS with IPv4 address so that your domain can be hosted for web services.
First of all you should know your VPS IPv4 address. Log into your client area, My servers tab and check the right sidebar. You will see an IPv4 label, with your dedicated IPv4 address. Let's say it is: 188.8.131.52
Next you should have your own active domain that you should point to our paid VPS server. Log into your domain registrars page (for example Godaddy, 123-reg.co.uk or any other place where you have purchased your domain) and find DNS records management panel (if you can't find it, please ask your domain provider for help).
In DNS records management panel for your IPv4 address you should choose record type: A
Enter your full IPv4 address (lets say: 184.108.40.206)
Save changes. Most DNS changes are visible within 24-48 hours after you have updated DNS records, so please be patient and wait for DNS propagation period.
Note: If you want to access your VPS via browser as website, it should be running Apache or similar web server, so make sure httpd or similar services are running and your web server ports (for example port: 80) is not blocked by your VPS firewall.
