1. Log into your domain registrar where you bought your domain and go to the DNS settings or DNS management page.
2. Add an A record to the following IP address: 18.104.22.168. Delete all other A records that do not point to this address. This is the only change you need to make – you do not need to change your name servers.
3. Click Settings from the dropdown for your Space to set your custom domain to yourdomain.com:
You’re done! Note that it can take 12-24 hours for your domain settings to propogate across the Internet.
