Dynamic Host Configuration Protocol (DHCP) is a network protocol that allows a server to automatically assign an IP address to your computer. Enabling DHCP can help prevent configuration errors by assigning a unique IP address to your computer, as well as prevent loss of service due to sharing the same IP address with another computer on your network.

Things You Should Know

• On Windows, open Network Connections, click your connection, expand its TCP/IP properties, then click "Obtain an IP address automatically."
• On a Mac, open the Network panel of System Preferences, click your connection, select "Using DHCP" from the menu, and then click "Apply."
