9.1 Overview
When browsing web sites or sending E-mail messages a domain name is used. For example, the URL
www.yahoo.com and the e-mail address [email protected] contains the domain name yahoo.com. Domain
names allow users to remember the address to a site without knowing the IP address. For traffic to be routed
on a network those domain names must first be converted to an IP address. When a domain name is entered
the domain is translated to an IP address by a Domain Name Server (DNS).
DNS translation poses the following challenges:
• There are a limited number of IP addresses currently available.
• Domain names and IP addresses are created and changed everyday.
Dynamic Domain Name System (DDNS) enables you to link a domain name to a changing IP address. When
you connect to the Internet, your Internet service provider uses Dynamic Host Configuration Protocol (DHCP)
and assigns the domain an unused IP address from a set pool of IP addresses. This IP address is only used
for the duration of this specific connection. This method of dynamically assigning addresses, increases the
pool of available IP addresses.
The DDNS service maintains a database to connect a domain name to an IP address on the Internet. Because
the IP addresses change, it is necessary to update the DNS database with the current IP address for a given
domain name. The DDNS service performs these updates.
Enabling Dynamic DNS will allow domain name information to be updated when the IP address associated
with that domain changes. When a MU associates and gets and IP address from the DHCP server the DHCP
server then updates the DNS server with the IP allocated to the corresponding hostname.
9.2 Enabling DDNS
Dynamic DNS is configured on a per-subnet basis and requires the subnet to be configured as a DHCP Server.
DDNS is then enabled and configured in the Advanced DHCP Server screen for the corresponding subnet.
1. From the Subnet screen for the desired subnet select the This interface is a DHCP Server option.
