Some of the name servers that hold domain names in them also support Dynamic DNS. Dynamic DNS helps in maintaining multiple or changing IP addresses for the same DNS or canonical name. This is possible when the IP addresses held by the name servers keep getting altered in real time. Dynamic DNS becomes a necessity when the server that is holding the program itself keeps changing. The Dynamic DNS is a facility by which the name server will keep track of the changing address. Under Dynamic DNS, the name server would help other computers to trace the server easily without them keeping track of it.
A name server can become a dynamic DNS server if it is loaded with dynamic DNS Server software. This software enables the server to offer the dynamic DNS service to its users. There is much proprietary software that provides these services. On the internet, you will also find free dynamic DNS software that would enable your name server to provide the dynamic DNS service. Both the free Dynamic DNS client and the free dynamic DNS service are part of the Dynamic DNS server software which has to be loaded on to the server. Once the server is loaded, both the services are offered from the server. Whether the software is obtained free or not, there are also versions that get charged for the purpose. On many occasions, intermediate hardware in contrast to the server is the one that would need dynamic DNS. Dynamic DNS Suse is made for the Suse branded equipments. Similarly, Dynamic DNS for Dlink and dynamic DNS for Symantec firewall are both units that make use of Dynamic DNS. These are made Dynamic because of the large scale gain in terms of the bandwidth needed. Dynamic DNS would help in minimizing the number of lines that are occupied if these had been dedicated DNS systems. This is an optimizer that would enable optimal use of the resources. More specifically resources that help in saving the bandwidth for the services and the number of lines needed to provide the service. Apart from these units, the dynamic DNS wireless routers that are provided by a number of manufacturers also make use of the same provision. This also helps in working in sync with the dynamic DNS systems.
