IP and DNS questions for ispconfig
i've installed ispconfig on fc4 successfully...
i have some questions regarding IP and DNS setup requirements...
1) if i intend manage a few (<10) sites using ispconfig, do i need 1 IP address for each site? or the sites can share the same IP address?
2) it seems like the server itself must have a fully qualified domain name, is it correct? if so, must i have a DNS record somewhere else that points to it before i can add new domains?
3) how can i setup the server in my intranet environment to familiarise myself before i put it on the internet for public access? or is this not possible?
