Instructions for the TCP/IP Connection Settings Worksheet
These instructions explain the settings in the worksheet that begins on page 9.
IP address
Enter the unique numeric address that identifies the server on the network. It’s written as four
numbers separated by periods (for example, 192.0.2.123).
If you have an AirPort Base Station or other Internet router that shares an Internet connection on your
local network, the server’s IP address must be on the same IP subnet as the IP address of the base
station or router, such as 10.0.7.2 or 192.168.99.2.
Subnet mask
Enter the group of four numbers that identifies the network part of the server’s IP address; the
remainder of the IP address uniquely identifies the server on that network. If the server has a private
IP address, use 255.255.255.0 for the subnet mask. If the server has a public IP address—it doesn’t
begin with 192.168, 10.0–10.255, or 172.16–172.31—get the subnet mask from the same source as your
server’s IP address.
Router
Enter the IP address of the router for the server’s local network (for example, 192.168.99.1 or 10.0.7.1).
The router is a device that forwards data packets from the local network toward their destinations on
other networks or the Internet. If you have an AirPort Base Station or other Internet router, use its
address. Otherwise, get the router address from the same source as your server’s IP address.
DNS servers
Enter the IP address of a DNS server (for example, 192.0.2.12) or a list of IP addresses of DNS servers. A
DNS server translates DNS names like server.example.com to IP addresses and vice versa. The DNS
server addresses will be set up automatically if you’re using a DHCP, PPPoE, or BootP method of
configuring the TCP/IP connection. If you’re configuring manually, get the DNS server addresses from
your ISP.
Search domains
May be supplied automatically by your DHCP service. You can also enter the last part of one or more
names that you want automatically appended to partial DNS names you enter while using the server.
For example, if you specify campus.univ.edu as a search domain, you can type server1 in the Finder’s
“Connect to Server” dialog to connect to server1.campus.univ.edu.
DHCP client ID
Enter the client identifier code if you received one from your ISP or network DHCP server
administrator. The client ID identifies the server (or the server’s network port, if the server has more
than one port).
PPPoE settings
Enter the account name and password you received from your ISP for making a PPPoE connection to
the Internet. Enter the service name if your ISP gives it to you; otherwise, leave the service name
blank. You may also enter your ISP’s name, but it isn’t required for making a PPPoE connection.
