General

You can get IP settings assigned automatically if your network supports this capability. Otherwise, you need to ask your network administrator for the appropriate IP settings.

Obtain an IP address automatically

Use the following IP address:

Advantages

IP addresses entered manually on each client computer

Possibility of entering incorrect or invalid IP address

Incorrect configuration can lead to communication and network problems

Administrative overload on networks where computers are frequently moved

IP addresses are supplied automatically to client computers

Ensures that clients always use correct configuration information

Elimination of common source of network problems

Client configuration updated automatically to reflect changes in network structure
