Calculate the subnet mask?

[praneeth.pj]

මචන් කව්රුහරි දන්නවද subnet mask 1ක් calculate කරන හැටි ip address එකකින්?

උදාහරණයක් 10.32.5.0

දන්නවනං හෙල්ප් එකක් දීපන්

11111111.11111111.11111111.11100000 = 255.255.255.224

The five 0's at the end can support up to 32 unique addresses which is enough for your maximum of 25 computers.

Remember that you're working with binary, so...

11111111 = 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255
11100000 = 128 + 64 + 32 = 224

---------------------------------------...

Here is another example to hopefully make some of this more clear:

11111111.11111111.11111111.11111100 = 255.255.255.252

This subnet mask would only allow four computers on the network to obtain an address. That's because the address space is defined by the trailing 0's. Since there are only two zeros the only possible unique addresses would be

00
01
10
11

The leading thirty 1's define the network itself and cannot be used to identify individual computers.
