Subnetting an IP Address
d12vzecr6ihe4p.cloudfront.netRemember, host bits are always the bits to the far right of the IP address. So when saving host bits, start with the far right bit (the last bit of the last octet) and count to the left. Remaining host bits are given to the network portion. For example, suppose that six host bits need to be saved.
