You will also notice that the total number of hosts available is
252
, which is 256 minus 2
times the number of subnets. The total hosts per subnet are
126
because two of the IP
addresses on each network are reserved for network and broadcast.
The example below shows the fourth segment being changed from 100 to 130.
Subnet Design
Because 130 is greater than the IP address range for subnet 1 (which is 212.132.115.001
to 212.132.115.126), the
Network Address
and the
Broadcast
A
ddress
have changed to
represent the second subnet of our two subnets. These are the addresses that are required
by any workstation’s IP configuration utility.
IP Addresses as Hex Values
You may prefer to view IP addresses as hex values instead of decimal. Click the
Show
Hex
button to toggle all addresses between
Hex
and
