Hi @benji1907. Welcome to GoDaddy Community! If you still the domain name in question set up on a hosting plan within GoDaddy, then you should be able to just update the A record for the domain to point back to that hosting. As for what IP to use for your A Record, you should be able to find that in the control panel for your hosting plan. Your WWW CNAME can usually just be updated to point to "@". If you get stuck, you can always reach out to our customer care team for assistance.
