5.2.5 Viewing DDNS Bindings
The DDNS Bindings tab displays mappings between client IP addresses and domain names. DDNS keeps
a domain name linked to a changing IP address. Typically, when a user connects to a network, the user’s ISP
assigns an unused IP address from a pool of IP addresses (usually done through a DHCP server). This address
is only valid for a limited time. The mechanism of dynamically assigning IP addresses increases the pool of
assignable IP addresses. DNS is a service, which maintains a database to map a given name to an IP address
used for communication on the Internet. The dynamic assignment of IP addresses makes it necessary to
update the DNS database to reflect the current IP address for a given name.
To view switch DDNS binding information:
1. Select Services > DHCP Server from the main menu tree.
2. Select the DDNS Bindings tab.
3. Refer to the contents of the DDNS Bindings tab for the following information:

left-hand side of the tab.
