How many bits do you need for a subnet size.

3 Antworten

Need to know subnetting off top of your head.

The minimum addresses needed is 2 bits for 4 addresses 2^(# of addresses) = 2^2 which used for pint to point links. Max addresses can go as much as class A IP address /8 so for maximum bits is 32-8 = 24 bit Weniger

If number of addreses required in a subnet is "N" , then you need 2 more (network and bcst addreses) in addition to "N". So "N+2" is rounded of to Next 2 to the power . For e.g if we need 64 addresses in a subnet then , 66 rounded to next 2 to the power is is 2**7 ie 128. so number of bits required is 7. Weniger
