Same IP twice in the network, what happens?

Question

What happens when two computers with the same ip occur in a network? Makes it a difference if it happens in a subnet or in a WAN?
Is the Operating System of any imprtance?

Seems I have to add that I know it won't work and that I know how the problem is solved.

Answer 1

The subnet mask defines how much of a network a client can view. There is a list of appropriate subnet masks on the Internet.

It may be possible to specify identical IP addresses for two clients on the same LAN as long as their subnet masks allow them to not communicate.

Typically if two clients can communicate on a LAN and they have the same IP adress, than one client would be able to communicate over the LAN while the other client would be disabled. This is a feature if Windows.

Answer 2

You cannot have 2 of the same addresses on the same network with the same subnet, you will an IP Conflict warning.

If you are using more than 2 computers on a network, you should enable DHCP on your router or server so that the IP's are dynamically given out and you dont have to worry about conflicts.

Answer 3

i think what happens depends on what Switch/router you are using, some switch/router would stop both the computer form getting connected to the network while some times the computer that comes later on is stopped form getting connected to the computer. the OS some times even gives warning about other computer with same ip.
I think the Os(Software) is not important in the outcome, the hardware layer of the network is what decides the outcome

Answer 4

Change your IP address or in a command prompt type "ipconfig /release" then "ipconfig /renew"
