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
