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.

5.2.6 Viewing DHCP Bindings
The Bindings tab displays addresses and expiration times. There are two types of bindings, manual and automatic. Manual
bindings map a hardware address to a IP address statically. Automatic bindings dynamically map a hardware address to
an IP address from a pool of available addresses.
