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.
TCP/IP on a Macintosh:
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.
following is a quick guide to configuring TCP/IP for MacOS computers.
Configuring TCP/IP in a Macintosh computer requires the following:
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:
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 .
9.0.4 and later should have no problem obtaining an IP address from the
have your IP addresses dynamically assigned using MacTCP; however, to do
so requires that the optional AppleTalk kit be installed.
You can also use these instructions to configure other computers on your
network with manual or static.
you are manually configuring for a fixed or static IP address, perform
Configuration using MacIP (optional):
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.
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:
Go to the Apple menu. Select Control Panels and then TCP/IP.
With the TCP/IP window open, go to the Edit menu and select User Mode.
Choose Advanced and click OK.
In the TCP/IP window, select or type information into the fields as
shown in the following table.
Using MacIP server
(select available zone)
Name server address: Enter the primary and secondary name server addresses given to you by your network administrator.
Enter your domain name; if you do not have a
domain name, leave
Close the TCP/IP control panel and save the settings.
Note: You can also use these instructions to configure other computers on your network with manual or static
