Configuration of a maximum interval between updates is also allowed. You can specify the hostname and IP address in a URL. Since most of these protocols consist of a simple HTTP command that specifies parameters such as hostname and IP address in the URL portion of the command, this feature takes the same generic approach. The most notable HTTP-based protocol is, but there are many others. #Dyn updater not updating softwareThe Dynamic DNS Support for Cisco IOS Software feature provides the capability of a proprietary HTTP-based protocol to generate or perform DDNS updates. #Dyn updater not updating updateThe two mechanisms to update this information are by using HTTP-based protocols such as or by using the IETF standard. The DDNS update can specify additions or deletions of hostnames and IP addresses. There are address (A) or forward RRs and pointer (PTR) or reverse RRs. All RRs having the same NAME, CLASS, and TYPE are called a Resource Record Set (RRset). Each node has a set (possibly empty) of Resource Records (RRs). The domain name identifies a node within the domain name space tree structure. All updates were made as external edits to a zone master file. The data was expected to change, but minimally. The DNS was designed to support queries of a statically configured database. Feature Design of Dynamic DNS Support for Cisco IOS Software.Information About Dynamic DNS Support for Cisco IOS Software Reloading the system may take a little longer in some cases, such as, if there are outstanding DDNS updates that need to complete. The DHCP server could be impacted minimally because of the time and memory needed in order to set up the DDNS update and get things started. Even if the update is done before sending the ACK to the client, it does not delay processing of other DHCP requests. The DHCP server continues to process DHCP client DISCOVER and REQUEST packets while waiting for the DDNS updates to complete. The default for the client is two attempts with a 5-second wait time between attempts. The performance of the DHCP client can be impacted when the Dynamic DNS Support for Cisco IOS Software feature is enabled, because of sending DDNS update packets and waiting for responses from the server (before sending the ACK to the client REQUEST) and the client (immediately after receiving the ACK and assigning the address to the interface).
