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 you 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], and 192.168.1.1 respectively*. * 192.x.x.x scheme is just for example and does not mean it has to be this network. -David On 3/7/06, Petre Bandac <petre@kgb.ro> wrote: > > On Tue, 7 Mar 2006 10:29:18 -0500 Anno Domini, the honourable Huy Ton > That wrote using one of his keyboards: > > > Reading the handbook and I've seen /24 appended to an IP address > > often.
