Two Patents were granted yesterday by the USPTO on DNS

Nominum, Inc received a patent on Systems and methods for providing DNS services

A system for providing a Domain Name System (DNS) service may include providing an agent for installation on a subscriber device. The subscriber device may be connected to the DNS service via an entry point device. The system includes receiving, from the agent, agent data indicative of a subscriber identifier and a unique identifier associated with the entry point device. The system may then determine, based on the agent data, a current Internet Protocol (IP) address associated with the entry point device and associate the unique identifier with the subscriber identifier. The system may then dynamically map the subscriber identifier to the current IP address and provide DNS service to the subscriber device based on the current IP address.

The second Patent granted yesterday to Limelight Networks, Inc.; is for a
Domain name service resolver

A domain name service (DNS) resolver returns Internet protocol (IP) addresses.

A connection with an Internet application or device receives domain name resolution requests that originate outside of the Internet.

A direct DNS resolver identifies IP addresses without referring to the Internet or using other DNS resolvers. An address store includes a predetermined list of domain names and corresponding IP addresses specified from a point remote to the DNS resolver.

The DNS resolver processes the domain name resolutions for the predetermined list of domain names differently than domain name resolutions for other domain names not on the predetermined list of domain names. At least part of the predetermined list is pushed to a destination upon receiving a resolution request for a domain name in the predetermined list of domain names, the request being of a type other than an authoritative resolution request to be performed by the direct DNS resolver.
