IP ADDRESS:3/24 Subnet mask:0 Network:0 Broadcast:255 Host min: 1 Host max: 254 Hosts:

Hi there, 

I would like to know how to calculate the subnet mask for subnetting in 4, 8 and 16 blocks? 

Please could you put the answers on the tables on the document attached? I need the answer on the last column for example: 255.255.255.192/26
