Chapter 4. Getting Started
In this chapter, our emphasis shifts from how TCP/IP functions to how it is configured. Chapter 1 through Chapter 3 describes the TCP/IP protocols and how they work. Now we begin to explore the network configuration process. The first step in this process is planning. Before configuring a host to run TCP/IP, you must have certain information. At the very least, every host must have a unique IP address and host name. You should also decide on the items below before configuring a system:
- default gateway address
If the system communicates with TCP/IP hosts that are not on its local network, a default gateway address may be needed. Alternatively, if a routing protocol is used on the network, each device needs to know what protocol it is.
- name server addresses
To resolve host names into IP addresses, each host needs to know the addresses of the domain name servers.
- domain name
Hosts using the domain name service must know their correct domain name.
- subnet mask
To communicate properly, each system on a network segment must use the same subnet mask.
- WINS server address
If you run a WINS server to resolve NetBIOS host names, every Microsoft system on the network should know the name and address of the WINS server.
The network administrator is responsible for making and communicating decisions about overall network configuration. If you’re the network administrator make sure you provide the necessary configuration information to the system administrators on your network. ...
