If you'd like your online store to show on your own domain at checkout (instead of *.RentMy.shop), then you need to edit the following DNS settings with your registrar:
The inputs with your domain registrar are:
The hostname is your hostname and '@' means the primary domain
Point your domain's main A record to IP 18.104.22.168. Once it is pointed correctly, you will be able to access your RentMy store, but there will be a SSL warning temporarily. The SSL certificate will be generated after the DNS is configured. Be sure to notify your Account Manager or RentMy Client Support once you have updated your DNS settings.
Additionally, you may also configure the www or any preferred subdomain with a CNAME to the main domain or an A record to 22.214.171.124.
If you are not certain how to handle this change, you should contact your domain provider to find out how changes might affect your DNS settings.
