Chapter 2: Planning Your Network
IP Addresses

ADSL2+ Gateway with VoIP

Since you use the Gateway to share your DSL Internet connection, contact your ISP to find out if they have
assigned a static IP address to your account. If so, you will need that static IP address when configuring the
Gateway. You can get that information from your ISP.

Dynamic IP Addresses

A dynamic IP address is automatically assigned to a device on the network, such as computers and print servers.
These IP addresses are called “dynamic” because they are only temporarily assigned to the computer or device.
After a certain time period, they expire and may change. If a computer logs onto the network (or the Internet) and
its dynamic IP address has expired, the DHCP server will automatically assign it a new dynamic IP address.

DHCP (Dynamic Host Configuration Protocol) Servers

Computers and other network devices using dynamic IP addressing are assigned a new IP address by a DHCP
server. The computer or network device obtaining an IP address is called the DHCP client. DHCP frees you from
having to assign IP addresses manually every time a new user is added to your network.

A DHCP server can either be a designated computer on the network or another network device, such as the
Gateway. By default, the Gateway’s DHCP Server function is enabled.

If you already have a DHCP server running on your network, you must disable one of the two DHCP servers. If you
run more than one DHCP server on your network, you will experience network errors, such as conflicting IP
addresses. To disable DHCP on the Gateway, see the DHCP section in “Chapter 6: Configuring the ADSL2+
Gateway.”
