DHCP is a 2 part system.

One machine is the DHCP server. That's where you make changed to dhcpd.conf.

The other machine(s) are clients. They request information for the
server. The server gives it an IP address bassed on the servers
configuration. That's the lease.

The server and the client remember this information for a predefined
time, configured at the server. When the lease expires, the client
requests a new one. The server won't give another client that address
untill the lease expires.

Client configuration is easy. Just use redhat-config-network to use DHCP
on that interface. Server is another story. There are lots of options to
deal with, and it varies from server to server.

That's incorrect. The DHCP server can be configured to always give a
particular machine the same IP address. Quite handy in fact.
