Viewing Ddns Bindings - Brocade Communications Systems RFS6000 System Reference Manual

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.
2. Select the DDNS Bindings tab.
