In the method, an entry of the domain name blacklist is read at a DNS resolver in a plurality of DNS resolvers. The entry specifies a policy for the DNS resolver to execute when the DNS resolver receives a request to resolve a domain name. Before the reading is complete, an updated entry of the domain name blacklist is received, a new record to the domain name blacklist is added, and the entry being read is placed into a garbage pool having a current version number. Independently from the reading of the entry, the current version number is incremented and a new garbage pool is created for the incremented version number. When the reading is complete, the current version number is assigned to the DNS resolver."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lock-free updates to a domain name blacklist","description":"A computer-implemented method updates a domain name system blacklist in a lock-free manner is disclosed.
