How can I serve a Kickstart file over the network without a DHCP server?

I want to install CentOS 5.5 on two systems. I have a kickstart file. I would like to install CentOS on a system using this kickstart file. I'm reading the instructions provided by fedoraproject.org and RedHat.com , but they suggest using a DHCP server. I don't want to set up a DHCP server right now, and I can't have DHCP traffic on this LAN. How can I make this kickstart available over the network without using DHCP to assign an IP and point to the file I know that it is possible to make the Kickstart file available over HTTP, FTP or NFS. How can I configure the RedHat installer to have an IP address on the network and grab the kickstart file from a remote server?
