TCP/IP Addressing

TCP/IP is the networking protocol software that allows your computer(s) to communicate with the Internet through individual address identification.  The TCP/IP software must be installed on each computer and “bound” to the Network Interface Card (NIC).   Then each computer must be configured with appropriate TCP/IP addressing parameters to allow for automatic (“Dynamic”) Ethernet IP address assignment by the DHCP server on your network or you must assign a static Ethernet IP address and the appropriate gateway and DNS IP address parameters to your NIC.

Configuring TCP/IP on a Macintosh: 

Be sure TCP/IP is installed and configured on your computer.   In order to configure TCP/IP on a Macintosh machine, you must have either Open Transport or MacTCP installed.  You must also have Built-in Ethernet or a third party Ethernet card and its associated drivers installed in your Macintosh.

The following is a quick guide to configuring TCP/IP for MacOS computers. Configuring TCP/IP in a Macintosh computer requires the following:

  • You must have either Open Transport or Classic Networking (MacTCP) installed.
  • You must have built-in Ethernet or a third-party Ethernet card and its associated drivers installed in your Macintosh.

Dynamic Configuration (recommended):

Dynamic Host Configuration Protocol (DHCP) enables dynamic addressing of devices with IP addresses.  To configure your Macintosh computer(s) (OS 7.5 - 8.5) for dynamic addressing do the following: 

1.

Go to the Apple menu. Select Control Panels and then TCP/IP.

Open Transport TCP/IP

2.

With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Basic and click OK.

3.

In the TCP/IP window, select “Connect via: Ethernet” and “Configure: Using DHCP Server.”

4.

Close the TCP/IP and Save the settings.

 

Note: If you want to use the Dynamic Host Configuration Protocol (DHCP) server on your network to assign IP addresses to your Macintoshes, you must be running Open Transport, standard in MacOS 8, and optional in earlier system versions. Mac OS 8.6 and later employing Open Transport 2.5.1 or 2.5.2  do not currently support DHCP therefore Static Configuration must be used.  Apple has fixed this issue with its release of Open Transport 2.6 now available on the Apple web site at http://www.info.apple.com/support/downloads.html .  

MacOS 9.0.4 and later should have no problem obtaining an IP address from the DHCP server.

You can have your IP addresses dynamically assigned using MacTCP; however, to do so requires that the optional AppleTalk kit be installed. 

Note: You can also use these instructions to configure other computers on your network with manual or static.

Static Configuration (optional):

If you are manually configuring for a fixed or static IP address, perform the following: 

1.

Go to the Apple menu. Select Control Panels and then TCP/IP or MacTCP.

Open Transport TCP/IP

MacTCP

2.

With the TCP/IP window open, go to the Edit menu and select "User Mode".  Choose "Advanced" and click OK.  Or in the MacTCP window, select Ethernet and click the "More" button.

3.

In the TCP/IP or MacTCP/ More window, select or type information into the fields as shown in the following table:

Option:

Select or Type:

Connect Via:

Ethernet

Configure:

Manually

IP Address:

 

Check with network administrator

Subnet mask:

Check with network administrator

Router or Gateway address:

Check with network administrator

Name server address:

Enter the primary and secondary name server addresses given to you by the network administrator

Implicit Search Path:

Starting domain name:

Enter your domain name; if you do not have a domain name leave blank.

 

4.

Close the TCP/IP or MacTCP Control Panel and Save the settings.

5.

If you are using MacTCP, you must restart the computer.   If you are using Open Transport, you do no need to restart.

Dynamic Configuration using MacIP (optional):

If you want to use MacIP to dynamically assign IP addresses to the Macintosh computers on your network you must install the optional AppleTalk feature set kit.

Once the AppleTalk kit is installed, you can configure your Macintoshes for MacIP. To configure dynamically using MacIP, perform the following:

Using Open Transport TCP/IP:

1. Go to the Apple menu. Select Control Panels and then TCP/IP.

2. With the TCP/IP window open, go to the Edit menu and select User Mode. Choose Advanced and click OK.

3. In the TCP/IP window, select or type information into the fields as shown in the following table.

TCP/IP Option:                                                     Select/ Type:

Connect via:                                                          AppleTalk (MacIP)

Configure:                                                             Using MacIP server

MacIP Server zone:                                              (select available zone)

Name server address:                                       Enter the primary and secondary name server addresses given to you by your network administrator.

Implicit Search Path:                                           Enter your domain name; if you do not have a

Starting domain name:                                      domain name, leave blank.

 

4. Close the TCP/IP control panel and save the settings.

These are the only fields you need to modify in these screens
