DHCP Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP settings of every computer on your home network. DNS Server Address DNS stands for Domain Name System, which allows Internet host computers to have a domain name (such as 3com.com) and one or more IP addresses (such as 18.104.22.168). A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a domain name is requested (as in typing “3com.com” into your Internet browser), the user is sent to the proper IP address. The DNS server address used by the computers on your home network is the location of the DNS server your ISP has assigned. DSL modem Ethernet IP address ISDN modem ISP DSL stands for digital subscriber line. A DSL modem uses your existing phone lines to send and receive data at high speeds. A standard for computer networks. Ethernet networks that are connected by special cables and hubs move data around at up to 100 million bits per second (Mbps). IP stands for Internet Protocol. An IP address, which consists of a series of four numbers separated by periods, identifies a single, unique Internet computer host. Example: 22.214.171.124. ISDN stands for Integrated Services Digital Network. An ISDN modem uses your existing phone lines to send and receive data at higher speeds than analog modems. Internet service provider. An ISP is a business that provides connectivity to the Internet for individuals, businesses, and organizations. LAN Local area network. A LAN is a group of computers and devices connected together in a relatively small area (such as a house or office). Your home network is considered a LAN. MAC address MAC stands for media access control. A MAC address is the hardware address of a device connected to a network. NAT Network address translation. This process allows all of the computers on your home network to use one IP address. Using the NAT capability of the Home Ethernet Gateway, you can access the Internet from any computer on your home network without having to purchase more IP addresses from your ISP. Print server A device that enables a printer to be shared across a network. The Home Ethernet Gateway can be used as a print server for your home network. 24 GLOSSARY PPPoE Point-to-Point Protocol over Ethernet. Point-to-Point Protocol is a method of secure data transmission originally created for dial-up connections; PPPoE is for Ethernet connections. subnet mask A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network (as opposed to valid IP address numbers recognized by the Internet, which must assigned by InterNIC).
