Looking for the best payroll software for your small business? The solution is Variable Length Subnet Masking (VLSM). Whatever makes logical sense for you is the right answer, Personally, I don't see the point in reserving x addresses (per subnet?) They do not match, so host A will send the packet to the router. use private addresses on your internal local area network, you can use a The IP address is thus expressed in a dotted decimal format (for example, 192.18.80.200), where the value in each octet can range from 0 to 255 decimal (or 00000000 11111111 binary). If we compare the network that was given by the registry authority to a country code, we will then create area codes out of the country code. #3) From the given subnet, we can also calculate the IP range of a particular network. That means we have room for 16 subnets out of the class B network; that leaves us with 12 bits for the host. For each class, "Range" specifies the range of decimal values for the first byte of the . We are dividing networks into subnets and then subnets contain hosts. This time we have 16 available minus 4 and that is 12; 2 to the 12th power is 4096, but we have to subtract the two reserved addresses and that gives us 4094 hosts for each one of the four subnets. host bits) New IP mask: 255.255.255.192 .
