not done subnetting for a while, as a quick reminder, say I have 10.1.0.0/20
I know this means I have 10.1.0.0 to 10.1.15.0 networks, all the possible subnets are 4096, what would be thre start and end addresses of these subnets ? as I cannot find 4096, it it using all the combinations in the second octect, then spliting the third, ie
For Class A network you have 8 network bit & 24 host bit. Since it was /20 mask to get subnet bits you substract (20-8) and remaining (32-20) 12bits are for host. Total still is 24 bits. Only thing you divided a single network with 16777216 host into 4096 network and 4096 hots each network.
if i have 10.0.0.0/22 network then 22-8=14 subnet bits and 32-22=10 host bit.
For class B 172.16.0.0/20 example then i have 20-16=4 subnet bit and 32-20=12 host bit.
For class C, 192.168.1.0/26 example i have 26-24=2 subnet bit and 32-26=6 host bit
