Please help me solving few thought questions
1) 255.0.0.0 is class A subnet mask which mean 255 network portion but in ip address we can only use upto 126.255.255.255, after 127 class b range starts?
2) If we buy an IP , after doing subnetting of that ip, how will i use my bought IP.. I mean i bought 192.168.0.0 and i subnetted it in 4 network , what will be the function of main IP i bought then?
Thank you....
