I have a number of computers in the office. They run everything from Windows XP (which I am getting rid of) to Windows server 2012.

I have installed Windows server 2012 with ADDS, DNS and DHCP servers.

My UFF hopefully finally goes in tomorrow and hopefully I will use the Cisco router as a bridge.

I have a range of IP addresses assigned to me.

I have 4 separate servers which I would like to use the different IP addresses.

One is being used as a Webserver Windows.
One is being used as a Webserver Linux.
One is being used as a Mailserver also Linux.
One will be used as a separate server for the general office internet.

I have managed to set up the domain add computers and users to the domain etc.

Is there some way to assign the separate external IP addresses to different computers using windows server 2012 DHCP or DNS services.  I have been trying to read this up but am unable to find any information in this regard so if someone could point me in the right direction I would appreciate it.

cheers
