iis 7 - Wildcard SSL on IIS7 - Does each site need it's own IP?

If I buy a Wildcard SSL Certificate for one domain, like: domain.com
and I have 40 sites, like apples.domain.com and pears.domain.com

All the sites are on the same IIS 7 server

Does each site need a unique IP address?

If yes, is there anyway around it?

Answer

No, they do not need to be on unique IP addresses.

Navigate to C:\Windows\System32\Inetsrv\ In the Inetsrv folder, run the following command for each of the other websites on the IP address that need to use the certificate:

appcmd set site /site.name:"{IISSiteName}" /+bindings.[protocol='https',bindingInformation='*:443:{hostHeaderValue}']

Replace {IISSiteName} with the name of the IIS site and {hostHeaderValue} with the host header for that site e.g. site.mydomain.com
