At my previous host my vps server came with 3 ip addresses which easily allowed for me to set up cpanel and host my nameservers and websites on the same server. So for example we would have ns1.namserver.com going to 1 ip, ns2.nameserver.com going to a second ip and a third ip for routing to domain names hosted on the server. How would I achieve a similar set with your services. It appears I can only assign 1 ip per droplet here with Digital Ocean?
