  • Supporting DNS security in a multi-master environment
    Patent number: 8681995
    Abstract: Multiple peer domain name system (DNS) servers are included in a multi-master DNS environment. One of the multiple peer DNS servers is a key master peer DNS server that generates one or more keys for a DNS zone serviced by the multiple peer DNS servers. The key master peer DNS server can also generate a signing key descriptor that identifies the set of one or more keys for the DNS zone, and communicate the signing key descriptor to the other ones of the multiple peer DNS servers.

  • Branch office DNS storage and resolution
    Patent number: 7567582
    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.

  • Name Challenge Enabled Zones
    Publication number: 20070283028
    Abstract: A method and system for implementing name challenge enabled zones is described herein. A DNS server receives an update from a client device. If the DNS server hosts an authoritative zone for the update, the DNS server determines whether there is a record for the host name. If so, then the IP address associated with the host name is determined. The IP address is compared to the source address of the client device sending the update. If the IP addresses match, then the update is accepted.
