Different web sites... same domain

[celtic]

Is it possible to have two or more independent web sites with the same domain?

For example:

www.boavistafc.net
forum.boavistafc.net
futsal.boavistafc.net

Within ISPConfig you are able to to this.

When you create a site within ISPConfig, use the desired subdomainname in the Hostname field and the domain name in the Domain field.

The following error occurred:

An SSL certificate does already exist for this IP.

For every IP-address you can use only one SSL-certificate (of course).
If you have more than 1 IP-address available, then you can use that for that website,
But first add this additional IP-address within ISPConfig within your IP list under Management > Server > Settings.

I only have one IP address given from my ISP. Does that mean that I cannot implement this solution on my server?

If so... why not?

Thanks

That you can use only one SSL certificate for each IP-address is inherent to the https protocol.

You can ask your ISP/DNS provider if they can provide you extra IP-addresses. If you have received a block of new IP-addresses, you can add those within ISPConfig under Management > Server > Settings.
After that use it, for your site.
