Autoconfiguration: DNS and DHCP Support 
(5181 KB)
This redbook describes the Domain Name
System (DNS) server and Dynamic Host Configuration Protocol (DHCP) server
support that are included in i5/OS™. The information in this redbook helps you install,
tailor, configure, and troubleshoot the DNS and DHCP support through examples.
Note: This
redbook has not been updated to include the new BIND 8 features, including
dynamic updates, that are available for V5R1. However, it is a good reference
for general DNS and DHCP concepts.
