how can i use one IPadress to four machines..?
thank you in advance

One public IP address (to access Internet)?
Or you mean One private IP address inside the local area Network?
All problems in computer science can be solved by another level of indirection,
except for the problem of too many layers of indirection.

No you cannot run several computers in the LAN with the same IP...
Why do you need it?

No you didn't.i saw this situation at my friends workstation..
three people having same ip address...
so this is my doubt..
thank you
If your trying to do what I think, then use some sort of broadcasting method (as games and things do to publish lan servers)
no, im actually going to have to go ahead and sort of disagree with you here, yeah. While its not 'technically' possible, adn certainly not adviseable for the average joe to do this, you can in fact have multiple NIC's on the same physical layer that all have the same IP. Here is how and why -
When a NIC starts the first thing ti does is broadcast a packet that basicalyl says I, 192.168.0.2, KING of all that I survey, THINK, therefore I AM. To which all the other NIC's with other IP's roll their eyes and continue happily transferring gay midget beastiality porn to their hard drives. However, one lonesome NIC notices that IT is 192.168.0.2 and pipes up with a packet that basicalyl says USURPER!!! Get thee hence foul spawn of MFC. To which the usurper tucks its tail between its legs and reports to the system that that IP is already in use.
But, lets say we have a usurper that is disconnected from the main network when it starts up, it can successfully anounce its precense on teh network, which goes unchallenged. Then a second NIC which is also disconnected does the same thing. Then for some unknown reason the two networks become connected. Both NIC's will recv() packets going to their shared IP, and they will both send() packets that appear to be from the same IP. The results are undefined.
Now as to why you would want to do this, lets say you have some BigHugeApp.exe or BigHugeData.bin to transfer to multiple nodes in a cluster. You can save significant bandwidth by having every node operate on the same IP. Then again, if you are runnign a cluster, you are probably writing your own file transfer code, in which case you can just use a broadcast IP.
