Abstract
Maintaining DNS records. A computing network system includes a local Domain Name Service (DNS) server connected to one or more local clients or resources at a local branch office in an enterprise network. The local DNS server advertises to the local clients or resources at the local branch office that the DNS server is authoritative. The DNS server receives record information for the local clients or resources. An attempt is made to forward the record information to an enterprise hub DNS server. The record information is stored persistently in a cache. Storing the record information persistently in cache may be performed selectively or non-selectively. When performed selectively, the record information is stored or not stored depending on some result or other action. For example, the result may be stored or not stored depending on the results of attempting to forward to an enterprise hub DNS server.
