I'm teaching myself all about TCP/IP and have a question. If I have the IP address on a network of 6.200.200.200 with the subnet mask 255.0.0.0 and second IP address of 6.200.200.201 with a subnet mask 255.0.0.0, obvisiously I can ping 6.200.200.200 from 6.200.200.201.

Okay, this is what I want to know, if I change 6.200.200.200 to subnet mask 255.255.0.0 why can I still ping it from 6.200.200.201? Isn't it now on a different Network ID?

Lastly, if I change 6.200.200.200 to subnet mask 255.255.255.0 why can I then NOT ping it from 6.200.200.201?

Bare in mind, this is a simple network with only a switch between the PC's (IP addresses), no routers etc.
