  • Publication number: 20210021566
    Abstract: In one embodiment, a method and apparatus for resolving domain name system queries using unique top-level domains in a private network space are disclosed. For example, the method determines that a domain name service query specifies a destination residing in a private network space rather than in a public Internet space. The method then routes the domain name service query to a top-level domain name service server associated with the private network space, without routing the domain name service query to a root domain name service server in the public Internet space. The top-level domain name system server resides in the highest level of a hierarchy of domain name system servers belonging to the private network space.

  • Patent number: 10802938
    Abstract: Concepts and technologies are disclosed herein for providing and using an accessory setting service. Accessory data can be received from a computing device in communication with an accessory. The accessory data can include a unique identifier associated with the accessory. Based upon the unique identifier, a determination can be made as to whether or not the accessory data relates to a new accessory. If the accessory data does not relate to a new accessory, settings data associated with the accessory can be generated and transmitted to a recipient. If the accessory data relates to the new accessory, accessory settings associated with the accessory can be identified and stored with the unique identifier as accessory settings data.
