3.4 DNS
DNS, Domain Name System enables computers and devices to be recognized over a
network based on a specific name instead of IP addresses.
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 DHCP and its existing configurations on the host server,
before enabling 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 Windows servers where DCHP and DNS are separate functions it is very
important to configure the DHCP server to communicate with the DNS in
order for the iServer’s Host Name to correctly respond. If you cannot access
the iServer using its Host Name, please contact your network administrator
to make sure the DHCP and DNS servers are linked together.
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 x can be any number from 1 to 254). See
Section 3.5.2.
Your PC’s IP address cannot be 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.
