syntax for ranges of ip's

what is the syntax for a ip's.

exactly how do i set up ranges using the ip's inside the ipchains. explain how to write 192.168.1.0 -> 192.168.1.255 as a range, and why exactly so that i could write any range i needed. thnx....

/me welcomes the last of the Mohikans:"A kernel 2.2 user!"

As for the IP ranges - that's nothing specific to ipchains/iptables,
but rather has to do with subnetting.

192.168.1.0 -> 192.168.1.255 is 192.168.1.0/255.255.255.0 or 192.168.1.0/24
255.255.255.0 or /24 means 24 bits from the beginng of the address must match.
