Hi, DigitalOcean only allows one IP per droplet, as far as I know. I just read a great article here ~ https://www.digitalocean.com/community/tutorials/how-to-install-ispconfig3-on-an-ubuntu-14-04-server ~ and I have a couple of questions. 1) How can ISPConfig work with only one IP address for host, DNS and client sites etc? 2) If it works with only one IP, how many sites? Is there a theoretical limit? 3) Can ISPConfig manage servers on multiple droplets? Is that the way you get over only having one IP address? Terence.
