1. A method for domain name resolution, the method comprising: obtaining, at a recursive domain name server, a domain name resolution request for a domain name; providing the domain name resolution request over a local communication channel to a co-located root domain name server based on a local policy, wherein the co-located root domain name server is operable to provide a network address corresponding to a co-located top-level domain (“TLD”) name server based on a TLD in the domain name resolution request, wherein the co-located TLD name server provides a network address corresponding to a co-located second-level domain (“SLD”) name server based on a SLD in the domain name resolution request, wherein the recursive domain name server, the co-located root name server, the co-located TLD name server, and the co-located SLD name server are co-located and integrated within a single deployable hardware device package; validating a response received by the recursive name server based on a Domain Name System Security Extensions (“DNSSEC”) certificate, wherein the recursive name server is configured to perform domain name resolution even when the DNSSEC certificate expires; and providing an internet protocol address for the domain name in the domain name resolution request based on a record stored in the SLD name server.
