Domain Name System requirements

Consider these software requirements to run Domain Name System (DNS) on your IBM® i platform.

The DNS feature, Option 31, cannot be installed automatically with the operating system. You must specifically select DNS for installation. The DNS server added for IBM i is based on the industry-standard DNS implementation known as BIND 9.

Start of change After DNS is installed, you must have Portable Application Solutions Environment (PASE) (5770-SS1, option 33) and OpenSSH, OpenSSL, zlib (5733-SC1, option 1) installed. After these software programs are installed, IBM Navigator for i handles configuring the current BIND implementation. End of change

If you want to configure a Dynamic Host Configuration Protocol (DHCP) server on a different platform to send updates to this DNS server, Option 31 must be installed on that DHCP server as well. The DHCP server uses programming interfaces provided by Option 31 to perform dynamic updates.
