Domain Controller in 8 Virtual Machines

Hello,

i have one single server and i am going to create 8 virtual machine ins same subnet,

i will use these 8 VM as 8 separate Active Directory.

my question is is possible to create 8 AD in same IP subnet like   

VM1:192.168.1.1      xx.com

VM2:-192.168.1.2    yy.com

VM:-192.168.1.3      zz.com

and the same IP subnet can be resolve in single DNS sever ?

like  192.168.1.1 to  xx.com , 192.168.1.2 to yy.com and so on??

is it possible to do above scenario will it work fine ? or should i use 8 different subnet ??
