1.2. Manual vs. Automatic TCP/IP Configuration

DisadvantagesManual TCP/IP Configuration Automatic TCP/IP Configuration

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
