RIght now my main machine has internal IP 192.168.0.1. MY other 2 machines are0.2 and 0.4 as of today. MY main ip changes every now and then and that makes all the internal IPs to change too.

HOw can i find out everytime all of my pc's internal ips's?

If you can install nmap I would try that.  If you have nmap installed, ping your LAN  e.g.

nmap -v -sP 192.168.1.*

should do the trick.  

Another idea would to be to open a terminal and issue a ping command.  From the machine your issue ping it will tell you the ip address of the machine you are pinging from.  The downside?  you'll have to do this on every machine.

Another idea would be to type ifconfig from the command line. The downside?  you'll have to do this on every machine and it'll only work for the *NIX ones.

Another idea, instead of using DHCP connections, set up all of your machines to use static IP addresses and you won't have to worry about this silly shit ever again.  Just a thought.
