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. -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.
