Hello Huy Ton That,

The "/24" is the bitmask. As stated previously, it's basically a shorter
notation than having to write out the whole subnet mask (i.e. 255.255.255.0=
)
associated with the IP address. Unfortunately, attempting to explain the
whole concept of netmasks is just too time consuming for a mailing list and
you really have to have an understanding of the Base 2 (binary) numbering
system to fully grasp the logic behind it. However, I will mention since yo=
u
will often see networks networked at a classful boundary, whenever you see
"/8", "/16", "/24", or "/32", this represents the networks
192.[1-254].[1-254].[1-254], 192.168.[1-254].[1-254], 192.168.1.[1-254], an=
d
192.168.1.1 respectively*.

* 192.x.x.x scheme is just for example and does not mean it has to be this
network.
