First, compile the kernel with IP aliasing if req'd. Kernel 2.4.x doesn't seem to have that as a separate option - it "just works" now, but 2.2.x did require that option compiled in. Once running with your shiny new kernel, activate aliases for your interface as follows: ifconfig eth0 192.168.1.1 ifconfig eth0:0 192.168.1.2 ifconfig eth0:1 192.168.1.3 ... So eth0 is the interface, :0 and :1 are aliases on it. Make ifcfg-eth0, ifcfg-eth0:0, ifcfg-eth0:1, etc files in /etc/sysconfig/network-scripts to start the aliasing each boot.
