ghaoufa,

Hope the following helps, as this confused me at first also. My study course didn't mention this, but I did see this on practice exams. Doing a search on the web (www.ipprimer.com/bitbybit.cfm) came up with the following:

Subnet masks are often abbreviated using a forward slash "/" and the number of "one" bits in the mask. For example, a network 192.168.1.0 with a subnet mask of 255.255.255.0 can be expressed as 192.168.1.0/24 (since 255.255.255.0 is 24 binary ones followed by eight binary zeros.) Therefore, a /25 subnet is a subnet with a mask of 255.255.255.128, and a /26 subnet has a mask of 255.255.255.192, etc.
