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 controller DDNS binding information:
1 Select Services > DHCP Server from the main menu tree.
