Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

you can bind a particular IP address to a MAC address like this...
host ns {
next-server marvin.redhat.com;
hardware ethernet 00:14:22:58:1D:4F;
fixed-address 207.175.42.254;
}
Are you asking about a user who puts in their own IP, instead of using DHCP. If so, then it will be a fixed IP, and DHCP won't be involved. DHCP will only hand out IPs to clients, who request one.
Or are you asking about a user who takes his machine off one network, using DHCP, and connects it to yours, where, initially, the client will try and renew the existing IP. In this case, DHCP should reject that request, and the client will then request a new IP, which will be the one specified in your DHCP configuration.
