There are two options:
Option One(Recommended)
You
can only change your domain Name Servers to ours, we have anycast DDoS protected DNS, in this case you can
use provided cPanel account to manage your DNS records and use our free
email service. All DNS records are already configured in this case and
you don't need more action.
Option Two
You should go to your
DNS server, elsewhere you manage your DNS records and Add or Edit your
domain A records to our reverse proxy IP. In this case you can't use our
free DNS management and email service.
