Edimax Technology ES-5240G+ guide

In this diagram, you can see the subnet mask with 25-bit long, 255.255.255.128, contains 126 members in the sub-netted network. Another is that the length of network prefix equals the number of the bit with 1s in that subnet mask. With this, you can easily count the number of IP addresses matched. The following table shows the result.

Prefix LengthNo. of IP matchedNo. of Addressable IP

/32	1	-

/31	2	-

/30	4	2

/29	8	6

/28	16	14

/27	32	30

/26	64	62

/25	128	126

There will be a maximum of 254 effective nodes exist along the sub-netted network. This network is considered to be a physical autonomous network that it owns a network IP address which may look like 168.1.2.0.

With the subnet mask, a big network can be divided into smaller pieces of network. If we want to have more than two independent networks in a worknet, a partition to the network must be performed. In this case, subnet mask must be applied.
