Abstract:
1. A method implemented in a non-transitory computer-readable storage medium to process on a node and to perform the method, comprising: listening, on the node, for a wild-carded Internet Protocol (IP) address and recognizing the wild-carded IP address as a Highly Available IP (HaIP) address that is bound to a network resource and decoupled from a physical interface, wherein the HaIP address migrates to the node when an original node that was used to resolve the HaIP address for original DNS requests fails to respond; receiving, at the node, a first Domain Name System (DNS) request; and communicating from the node and over a network with a directory service for a directory maintained by the directory service, communication with the directory service indicates that the first DNS request was received on the wild-carded IP address, the first DNS request is asked to be serviced from the directory service that maintains DNS data for the directory, and wherein the directory service is external to the network node over the network, and wherein subsequent DNS requests are serviced from the node; acquiring, on the node, the DNS data from the directory service; and rebuilding, on the node, a directory tree for the directory using the DNS data to directly service from the node the subsequent DNS requests node.
