TCP/IP is a way of specifying how information is transferred over the Internet. It is a standard that is independent of the operating system.

You can make the AppleShare IP server available over TCP. Doing so has the following benefits:

•	You can offer Web services through the AppleShare IP server. With AppleTalk alone, you cannot set up a Web server.
•	Shared items are easier to access for Windows clients.
•	It's faster to log on to a server using the Chooser.
•	If your server is connected to the Internet, you can make services available to remote users.
•	You can offer Windows printing (LPR).
•	You can administer AppleShare IP services using Mac OS Server Admin.
•	You can set up shared users and groups.

Using AppleShare IP over TCP

If you want client computers to use AppleShare IP services over TCP, you must set up TCP on each client.

Note: If you use TCP to make services available to remote users, you won't have as high a level of security as you would if you restricted services to local users.

Setting up a private TCP/IP network

If you aren't connecting your network to the Internet, you can set up TCP/IP on your network without obtaining an official Internet address and domain name. You assign the computers on your network private IP addresses from a specified range of addresses.

IMPORTANT: If you think you might connect to the Internet in the future, you should register with an Internet registry now and use the IP addresses provided by the registry. Otherwise you'll need to set up every computer on your network later. For more information, contact your network administrator, Internet service provider (ISP), or an Internet registry service.

If your TCP/IP network will never be connected to the Internet, you can assign addresses to the computers on your network from the ranges listed below without consulting any Internet registry.

•	10.0.0.0 to 10.255.255.255 for Class A networks
•	172.16.0.0 to 172.31.255.255 for Class B networks
•	192.168.0.0 to 192.168.255.255 for Class C networks

An address with all bits set to 0 refers to the network itself. An address with all bits set to 255 is a "broadcast address" and goes to all computers on the network.

For example:

•	192.168.0.0 refers to the Class C network 192.168.0.
•	192.168.0.255 is the broadcast address for the Class C network.
•	192.168.0.1 to 192.168.0.254 are the addresses of individual computers on the Class C network.

If you do not have a router connected to your network:
You should enter a router number in each computer's TCP/IP control panel. Use the server's IP address, the computer's IP address, or 127.0.0.1.
