[ QUOTE ] there si a way to make a definition of a range of ips?
i.e. from 10.0.0.1 to 10.0.0.25
[/ QUOTE ]Netmasks work on the power of 2 principle. It is therefore not possible to make a netmask for the range 1 - 25, but it is very easy to make a netmask for the range 0 - 31.
As an example, the address range 10.0.0.0 to 10.0.0.31 is defined by the netmask 255.255.255.224. This can also be written as 10.0.0.0/27.
