Subnetting
Dear friends am confused with the logic behind subnetting. i am learning from video tutorial and quite didn't get it
so my question is as below
After subnetting class c address by borrowing one bit from host to network , it leaves host with 7 bit and network increases bit to 25 bits .
According to my video tutorial it stated that theoretically class C address has
one network and 255 hosts. And after subnetting 2 networks with 127 hosts. but i dont think so ....
i believe class c has around 2097150 network and 255 hosts. i didn't get that logic . please help me get that right in my head.
so my question is as below
