ejaboneta Posted September 30, 2010 Share Posted September 30, 2010 We just bought a virtual dedicated server from GoDaddy and they offer 3 free IP addresses. I was thinking about using one IP just for our email. But I could probably just use one IP for everything. I've never really set up web and email servers so my question is, why would I need 3 IP addresses? Any benefits or disadvantages?

trq Posted September 30, 2010 Share Posted September 30, 2010 There are lots of different uses for multiple IP addresses. The first probably being that I would use a dedicated IP address for ssh access, another dedicated to standard web. This way you can have only the ports required to be open on there corrisponding ip's. SSL also comes to mind. While there is now progress being made with ways to host multiple SSL certs on a single IP address, it is still general practice to have one cert per IP (and may still be the only way to do it, I haven't actually looked into this for a long while). In short, I would be inclined to use one IP for admin purposes. ssh, svn, ftp access etc etc, another for public web, and keep the other for the case where your running multiple sites.
