Subneting class c addresses **Normal Way!**

Before i start this article  i should say don't worry if you can't understanding it! you can see the fast way!

- In class C address, only 8 bits are available for defining the hosts.
- Remember that subnet bits start at the left & go to the right without skipping bits.
- This means that the only class C subnet mask can be following.

Binary                    Decimal                    CIDR
00000000                    0                              /24
10000000                    128                          /25
11000000                    192                          /26
11100000                    224                          /27

** We can't use /31 or /32 because we have to at least 2 host bits for assigning IP address to hosts
