Network Configuration Concepts | 45 |
Network | The following sections explain certain key concepts of configuring your |
| Configuration | network, which you must understand in order to set up the Webcache |
| Concepts | successfully. |
| IP Addresses | If you are uncertain about what IP addresses to assign your equipment, |
| contact your network administrator. |
| To operate correctly, each device on your network (for example a |
| webcache or management station) must have a unique IP address. IP |
| addresses have the format nnn.nnn.nnn.nnn where n is a decimal |
| number between 0 and 255. An example IP address is ‘192.168.100.8’. |
The IP address can be split into two parts:
■The first part (‘192.168’ in the example) identifies the network on which the device resides.
■The second part (‘100.8’ in the example) identifies the device within the network.
If your network is internal to your organization only, you may use any arbitrary IP address. We suggest you use addresses in the series 192.168.100.X (where X is a number between 1 and 254) with a subnet mask of 255.255.255.0.
These suggested IP addresses are part of a group of IP addresses that have been set aside specially for use “in house” only.
CAUTION: If your network has a connection to the external IP network, you must apply for a registered IP address. This registration system ensures that every IP address used is unique; if you do not have a registered IP address, you may be using an identical address to someone else and your network will not operate correctly.
Obtaining a Registered IP AddressInterNIC Registration Services is the organization responsible for supplying registered IP addresses. The following contact information is correct at time of publication:
