Dynamic Host Configuration Protocol, or DHCP for short, is a protocol that enables your MacBook to retrieve all the networking information you need. Before you can use DHCP, you have to add a DHCP server, which provides other computers on the network with their configuration settings. Most Internet connection-sharing hardware devices (and software-sharing implementations as.

Manually Configuring Network Settings
Network connections, when automatically configured, seem to work almost like magic. Your computer finds a signal (wired or wireless), makes a connection, and everything just “works.” Behind the scenes, however, there are a handful of network settings that make this happen. If a network doesn’t support auto-configuration, using a protocol known as DHCP, you need to make these settings manually.
Your network administrator needs to provide the following settings in order to manually set up your network:
- IP Address—A numerical address that uniquely identifies your computer.
- Subnet Mask—A value that helps your computer determine what network it is on.
- Router—The address of a device that moves network traffic between other local computers and remote networks (such as the Internet).
- DNS—The address of a device providing domain name lookups to your network. This service translates human-readable names (such as www.apple.com) into IP addresses and vice-versa.
- Proxy Settings—A device that sends and receives network traffic on your behalf, acting as a middleman for services.
Configuring TCP/IP and Proxy Settings
To manually change your TCP/IP and Proxy settings, follow these steps:
- Open System Preferences and click the Network panel icon.
- The network panel opens, showing all the available interfaces. Click the interface you want to configure (usually Ethernet or Wi-Fi).
- Click the Advanced button to view the full manual interface for network settings.
- The Advanced configuration screen appears. Click TCP/IP in the button bar to access the common TCP/IP network settings.
- Use the Configure IPv4 drop-down menu to change your settings to be configured Manually.
- Enter the IP Address, Subnet Mask, and Router, as provided by your network administrator.
- Click DNS in the button bar to change your domain name server settings.
- Click the + button below the DNS Servers list to add a new server to the list. Your ISP or network administrator usually provides at least two addresses to use; be sure to type it exactly as provided. (Use the – button to remove unused DNS Servers. Search Domains are not required unless specified by your administrator.)
- If your network requires the use of a proxy, click the Proxies button in the button bar. If not, skip ahead to step 13.
- Click the checkboxes beside the protocols that you want to configure.
- Click the protocol names to configure each proxy. Setup fields appear to the right of the protocol list.
- Enter the proxy information as provided by your network administrator.
- Click OK to exit advanced setup.
- Click Apply to activate and begin using your new network settings.
Activating PPPoE for DSL Connections
In some cases, most typically when using a DSL modem, you need to activate PPPoE (Point-to-Point Protocol over Ethernet) in order to make a connection.
- Open System Preferences and click the Network panel icon.
- Select your active Ethernet Interface.
- Choose Create PPPoE Service from the Configure IPv4 dropdown menu.
- Choose a name for the connection. (The default, PPPoE, is fine.)
