METHODS AND SYSTEMS FOR DYNAMIC DOMAIN NAME SYSTEM (DDNS)

摘要

A method carried out by a network node for sending update messages to a server when a predefined event occurs or periodically. The network node comprises a plurality of network interfaces. The update message is embedded with a unique identifier corresponding to the network node, and a network interface identifier corresponding to at least one of the plurality of network interfaces. In particular, the network interface identifier is corresponding to network interface(s) at which a predefined event has occurred. The present invention further comprises a method carried out by a server for resolving a DNS request by retrieving DNS resource records of a network node and/or network interface specified in the DNS request, and replying to the DNS request with the DNS resource records. The DNS resource records are created based on in part at least one update message received from the network node.
