Abstract:
1. A domain name service (DNS) resolver for returning Internet protocol (IP) addresses, the DNS resolver comprising: a connection with an Internet application or device, wherein the connection receives domain name resolution requests that originate outside of the Internet; a direct DNS resolver that identifies IP addresses without referring to the Internet and without using other DNS resolvers; an address store, wherein the address store comprises a predetermined list of domain names and corresponding IP addresses that are specified from a point remote to the DNS resolver, wherein 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; and a cache of domain names different from a predetermined list of domain names, wherein 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.
