limit traffic based on IPs

[binary dreamer]

stuck big time with the syntax of an iptable.
i would like to permit the speed of 512/512kbps to ips 192.168.1.2-5
i would like to permit the speed of 1024/1024kbps to ips 192.168.1.6-10
i would like to permit the speed of 2048/2048kbps to ips 192.168.1.11-12
the rest of the ips will set to free traffic
