Understanding IP Addressing
Posted on 2007-07-26
I'm teaching myself all about TCP/IP and have a question. If I have the IP address on a network of 188.8.131.52 with the subnet mask 255.0.0.0 and second IP address of 184.108.40.206 with a subnet mask 255.0.0.0, obvisiously I can ping 220.127.116.11 from 18.104.22.168.
Okay, this is what I want to know, if I change 22.214.171.124 to subnet mask 255.255.0.0 why can I still ping it from 126.96.36.199? Isn't it now on a different Network ID?
Lastly, if I change 188.8.131.52 to subnet mask 255.255.255.0 why can I then NOT ping it from 184.108.40.206?
Bare in mind, this is a simple network with only a switch between the PC's (IP addresses), no routers etc.
