The DNS update process is the process of adding, changing, or removing a Resource Record (RR) in a zone’s master file. The classic method of updating RRs is to manually edit the zone file, and then, in some implementations, stop and start the name server so that the zone files can be read and the appropriate modifications can be made to those files. However, this approach is not feasible when the number of modifications would be so great as to inhibit the DNS server from answering queries. Therefore, another mechanism is used to enable real-time, dynamic updates to entries in the DNS database. This mechanism is called Dynamic DNS (DDNS). By using this mechanism it is possible for the name server to change one or several records in one particular zone by using just one DNS update request, while at the same time, responding to user’s queries.
