Chapter 5 - DHCP Controls and Reporting

Dynamic Host Configuration Protocol

DHCP allows clients to obtain IP network configuration, including an IP address, from a central DHCP server. DHCP servers control whether the addresses they provide to clients are allocated permanently or leased for a specific period of time. When the server allocates a leased license, the client must periodically check with the server to re-validate the address and renew the lease.

The DHCP client and server programs handle address allocation, leasing and lease renewal.

If you are using DHCP on your System i5 this gives you a way to control it. If you are not using DHCP, you can still use these options to review other activity.

To use the System i5 as a DHCP server, refer to the relevant OS/400 manual and/or Operations Navigator.
