ddnsStatus
Module: CME-MIB
OID (symbolic): CME-MIB::ddnsStatus
OID (numeric): 1.3.6.1.4.1.2.3.51.2.4.9.1.10
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: Dynamic DNS provides the capability for a networked device to notify a domain name server to change, in real time, the active DNS configuration of its configured hostnames, addresses or other information stored in DNS. With Dynamic DNS, host computers gain the capability to notify their respective DNS server of the IP address they have received from a DHCP server or through self-configuration.
What is ddnsStatus?
This read-write object enables or disables Dynamic DNS, which lets the networked device notify a DNS server in real time to update the active DNS records for its hostname whenever its IP address changes, such as after a DHCP renewal. An administrator enables this so the management module's DNS entry stays accurate automatically even if its DHCP-assigned address changes, without manual DNS record updates. For example, an admin enables DDNS so that after the management module's DHCP lease renews with a new address, its hostname in DNS updates automatically instead of pointing to a stale IP.
