Thank you for your input! We will consider this functionality in upcoming releases if it will be popular.
Everyone, please continue voting for this feature if you consider it important.
+1 from me. It woult be great to have it in Plesk
This seems to be important, so we’ll address it in one of the upcoming Plesk releases.
Please continue to vote so we can accurately assess the popularity of this request.
The idea is under review now.
We would like to learn from you how you will use it. i.e. different domains on different IPs for SSL (but did you know about SNI?), or for subdomains? for aliases? Why an alias would need another IP?
Thanks for all your answers and votesGrzegorz commented
Having multiple shared IPs would allow to mitigate DDoS attacks when server room is using blackholing. Having multiple shared IPs per website would allow to use DNS based round robin and allow website to be available even during blackholing running on one of this IP addresses.
Even having possibility to bing all websites to *:80 would be usefull because DNS templates can be altered to allow creation of multiple A records with various IP addresses.
