  • Publication number: 20180219831
    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: 9876826
    Abstract: A system for providing an architecture for enabling internet protocol (IP) carrier peering is disclosed. The system provides mechanisms for providing carrier telephone number mapping (ENUM)-based routing for subscribers of a first carrier to locate and connect with subscribers of another IP peering carrier. The system may receive an IP call from a first device of a first carrier that is destined for a second device of a second carrier. The call is forwarded to a breakout gateway control function/transit function that initiates a modified ENUM query to an internetwork packet exchange partner (IPX-P) network using an intercarrier ENUM apex domain. To retrieve a record for routing the call, the modified ENUM query is sent to an IPX-P ENUM via a domain name service name server record configuration directing to the IP address of the IPX-P ENUM. Based on the record, the call is then routed to the second device.
