The IP address you’ve used as an example would not work. That is a ‘local’ address, ie home address. If you want DNS to resolve your public domain name to your home server, you need to set the A record to your ‘public’ IP address, ie the external address of your modem/router. Find this by going to whatismyip.com or something similar.

That will connect your domain name with your router. You then set up port forwarding on the router to pass requests to the server.
