Connect to Wired Network

If you want to connect your Mac to a network using a cablefor example, if youre connecting toffice network, a cable modem, or a digital subscriber line (DSL) modemfollow the steps belo

connected.

Step 1: Gather Information

To set up your network connection, you might need the following information:

What is my user or account name and password?

Does my Mac receive its IP address manually or automatically?

If automatic, is it assigned using DHCP or BootP?

If manual, what is the IP address, subnet mask address, and router address?

For some networks and ISP: What is the DHCP service name, and what is the DNS name?

Your network administrator or Internet service provider (ISP) can give you this information.

Definitions

DHCP and BootP: Both are protocols (rules or languages) that govern how devices on a networ

with each other. Dynamic Host Configuration Protocol (DHCP) and BootP (Bootstrap Protocol) en

automatically assign an IP address to a computer.

IP address: Internet Protocol address. Numerical label assigned to each device (e.g., computer,

participating in a computer network.

Step 2: Connect your Mac

Depending on the type of equipment you have, connect the other end of the Ethernet cable to y

office networks Ethernet device (such as a hub or router), or to the cable or DSL modem provid

Internet service provider (ISP).

FTP (File Transfer Protocol)Example address: ftp://DNSname

DNS Name or IP Address?

You can enter the Internet Protocol (IP) address for the computer or server rather than its DNS (

System) name. Example: 92.123.149.15 = apple.com.

Because domain names are alphabetic, they're easy to remember. However, the Internet is reallnumerical IP addresses. Every time a domain name is used, a domain name system translates th
