You can connect any top-level domain to your Vsble account with the Vsble PRO plan. A top-level domain is one that can be used with the www. prefix ( www.yourname.com). Either you already have a domain, or you can buy one for a small fee from a domain provider like GoDaddy, Ionos, or Namecheap (there are many out there - see the list of recommended providers).
To connect a domain, you need:
Add two A-Records in the DNS Settings of your domain control admin panel of your domain provider.
1. Record type: A Host: @ Value: 220.127.116.112. Record Type: A Host: www Value: 18.104.22.168
(Below how the records look like - ex. GoDaddy)
Any other A-Records for the @ and www with a different IP will block the domain connection. Also remove any AAAA records.
Add the domain name in the website section of Vsble and "click confirm change". Wait until the domain connects and SSL is issued.
