Can 2 computers communicate without an IP in same LAN?

Question asked by visitor Rajiv

Yes, IP address is used only if we use IP protocol at network layer. If we are not using TCP/IP in LAN, the ip address is not required. ie. Apple Talk.

yes brother you can connect the two systems without any ip address through connecting the console cable(which who have 9 wires) and always use in the router to router connectivity

Jeez, you should look up computer history. NetBeui did this long before IP existed.

There's always a crossover cable.

etc.

I don't think that two computers can operate without IP in same LAN.
If computers have to communicate (send data) they need to have some application layer protocol running on them for that. It means that every layer of TCP/IP come into picture while communicating, you just cant skip N/w layer.
In case I am wrong let me know that...

If we don't assign IP address to computer it'll automatically take APIPA address. e.g.
169.254. X.X & subnet will be 255.255.0.0
When my NW is 16 bit it mean both the computer are is same network? Them why the 2 computer will not communicate if i connect them by cross cable?
