First Claim
Patent Images
1. A method to resolve domain names through a managed sinkhole distribution, the method comprising:
- initiating a top level domain (TLD)zone update at a first authoritative name server, the zone update includes one or more top level domain zone file changes for a target domain that redirects a query for an Internet Protocol (IP) address for the target domain to one or more authoritative name servers associated with a sinkhole island instead of directing the query to a second authoritative name server for the target domain that is different from the one or more authoritative name servers; and
subsequent to the zone update, receiving the query for the IP address for the target domain by the one or more authoritative name servers associated with the sinkhole island that is one of a plurality of sinkhole islands associated with a sinkhole, each of the plurality of sinkhole islands being distributed and operating independently from another sinkhole island of the plurality of sinkhole islands and the query for the IP address for the target domain is in response to a request for the IP address from a source,wherein the one or more authoritative name servers associated with the sinkhole island is configured to access a database for the IP address for the target domain and return an IP address for a sinkhole sensor node within the sinkhole island to the source that initiated the request for IP address.

19. A system to provide a managed sinkhole distribution scheme, comprising:
-
one or more authoritative name servers associated with a sinkhole island of a plurality of sinkhole islands, the one or more authoritative name servers to receive a query generated in response to a request for an Internet Protocol (IP) address for the target domain subsequent to a top level domain (TLD) zone update that redirects the query to the one or more authoritative name servers instead of a first authoritative name server for the target domain that is different from the one or more authoritative name servers, each of the plurality of sinkhole islands being distributed and operating independently from another sinkhole island of the plurality of sinkhole islands; and a database accessible by the one or more authoritative name servers associated with the sinkhole island, the database being accessed for the IP address for the target domain and, upon locating the IP address for the target domain, returns an IP address for a sinkhole sensor node within the sinkhole island to the one or more authoritative name servers for routing to a source that initiated the request for the IP address, wherein each of the one or more authoritative name servers includes a processor and a memory. - View Dependent Claims (20, 21, 22, 23, 24, 25, 26, 27)
