Hi Guys,
I buyed a domain in Godaddy and after I buyed a DNS Service in NO-IP. My home webserver is connect to internet with an Dynamic IP
With ISPConfig 3 my domain works!

))))
But now I have to create several subdomain as:
user1.mydomain.com
user2.mydomain.com
......
......
userN.mydomain.com
I saw is possible create subdomain with ISPConfig
MY FIRST QUESTION
when I create a subdomain create a subdirectory to my directory website?
I mean if my website is in this directory
ispconfigdirectory/client1/web1
my web domain is in this directory?
ispconfigdirectory/client1/web1/subdoman1
or I can create a dedicated directory outside this path?
MY SECOND QUESTION (I apologize for my incompetence)
I have to buy the subdomain in Godaddy? Each subdomain have a different IP?
thank you in advance,
Sal
