3.4 DNS

DNS, Domain Name System enables individual computers and devices to be recognized

over a network based on a specific name instead of an IP address.

For example, instead of having to use http://192.168.1.200 (IP address), you would use

only http://z03ec or any sixteen character name stored as Host Name under Access

Control menu in the zSeries Home Page.

The default DNS name for the Coordinator is "z" followed by the last four digits of the

MAC address of that particular Coordinator.

1. It is very important to communicate with the network administrator in order to

understand the DHCP and its existing configurations on the host server,

before enabling the DHCP on the Coordinator.

2. The Coordinators are shipped with a default static IP address of

192.168.1.200 and Subnet Mask of 255.255.255.0.

3. On Novell networks or Windows 2000 where the DCHP is an updated

function of DNS this feature may be beneficial since a particular name can be

assigned eliminating the need for the IP address.

3.5 IP Address

Every active device connected to the TCP/IP network must have a unique IP address.

This IP address is used to establish a connection to the Coordinator. Every computer

using TCP/IP should have a unique 32-bit address which is divided into two portions, the

network ID and the host ID. For instance, every computer on the same network uses the

same network ID. At the same time, all of them have a different host ID. For more details

about the IP address see Appendix B.

3.5.1 Default IP Address

The Coordinator is shipped with a default IP address of 192.168.1.200 and Subnet Mask

of 255.255.255.0. If you are going to use a Web browser or Telnet program to access

the Coordinator using its default IP address, make sure that the PC from which you’re

establishing the connection has an IP address that is in the same range as the

Coordinator’s IP address (192.168.1.x, where xcan be any number from 1 to 254). See

Section 3.5.2.

Your PC’s IP address cannotbe the same as the Coordinator ’s IP address.

You also need to make sure that your PC’s Subnet Mask is 255.255.255.0. This is a

good way to access the Coordinator over the network and make any configuration

changes needed. If 192.168.1.200 is already in use on your network, use an Ethernet

crossover cable between your computer and the Coordinator to change the IP address or

any other settings within the Coordinator.
