I have a cpanel server with 4 IP addresses. 1 is shared IP and other 3 are dedicated IPs. I want to change these 3 dedicated IPs to shared IP. How can I change it?
Yes. I have added the domains in reseller accounts and then shared the IPs

In the coming months I'll be creating different websites. Actually, one has been up already for awhile but I shut it down because of internet issues.
My issue now is I want to create another website but just under a certain sub-domain. I want to do this so that I can maximize my domain. So I'll be creating say:
1. www.example.com
2. api.example.com
3. xyz.example.com
My home router forwards port 80 to a certain local IP 192.168.0.3 which is a virtual machine. I want to make contents of different websites to reside in different VMs to avoid conflicts. So those 3 websites, are in different VMs.
Now, how can I set my router to target a VM depending on the website being requested provided that my router only targets one IP to port forward port 80?
Am I correct that I'll be using reverse proxy of Apache2?
Update: Is this an ideal solution on websites with this setup? If not how is large corporations set it up?
first you have to configure the dns server of your domain to forward all domains to the same ip address (use some a A-Records)
a-record
and then configure Name-based virtual hosts in the configuration of your apache webserver.
Name-based virtual hosts
in this Virtual hosts you can forward to the VMs
I have a user account with dedicated ip address on cPanel (WHM) and a website e.g. www.domain1.com is running on that. If i use same ip address to point some external domain www.domain2.com to that account ip without adding it as addon domain, it serves the website present on that ip (www.domain1.com) on www.domain2.com. How can I restrict that if possible?
You can't really 'prevent' it - for example, I could buy a domain name and point it at your website.
However, what you can do is add a 'redirect' to your site. So, if the domain used to access your site is not your domain, then redirect the client to your domain name
I don't really know cPanel, but this appears to be what you want

I have a dedicated server with 16 IPs. I wanted to know if its possible to install multiple web servers running off the different IPs. What would be the best way to do this? (I believe its possible, because how do web host reseller sites do it?). I am using CentOS 6. Thanks
Most host or resellers do not have one IP for each website; instead they use virtual hosts to allow one web server to serve multiple domains.
Once a process is listening on port (for example, port 80 which is HTTP) of an interface, that's it - you can't have another server or process listening on the same port.
As you have 16 IPs, you can run 16 servers - one listening on port 80 at each IP address.
Then further, each server can host multiple websites as virtual hosts.
You don't need 16 IPs though - you can host multiple websites using one IP.
I am trying to configure a remote server to host two or more development sites. My current approach was:
Hostname: somedev.something.somethingelse.com
Desired site 1: dev1.somedev.something.somethingelse.com
Desired site 2: dev2.somedev.something.somethingelse.com
I modified my hosts file so that:
dev1 127.0.0.1
dev2 127.0.0.1
I created a wildcard SSL certificate for my domain, and configured the bindings to use that SSL certificate.
However, while on the box locally I can access my sites at the desired sites, how can I expose this such that I can browse remotely?
You will either need to use a public DNS server to point those DNS names to the server's public IP address, configure your existing DNS server to point those names to the IPs (if you have a DNS server), or modify the hosts file on the machines you want to access it to point those names to the server's IP address
I have 17 sites with a multisite installation and uses the domain access module. This means that I have the same code base and same database for all 17 sites.Is it possible to configure Apache(hosting server) in such a way that all sites have a different IP even if the physical location for all sites is same?
Sure, if your server is set up to accept traffic for each IP, you just need to use IP-based VirtualHosts instead of name-based VirtualHosts.
Namely, you'll need to have Apache Listen directive for each IP address in apache.conf, and each VirtualHost block would have to reference the IP address its listening on.
