Abstract:

Systems and methods for instantaneously updating a DNS system database containing DNS records using partitions and atomic switching are disclosed. In one or more implementations, the system may include clients, a network, and a DNS system. Clients may communicate with the DNS system using the network in order to provide DNS record updates to a DNS system database. The DNS system includes distributed denial of service (“DDOS”) protection proxies, a firewall, and zone relays, allowing clients to specify which name servers are authorized to communicate with the DNS system. The DNS system also supports bulk updates of DNS records without causing clients to experience a reduction in performance, by writing DNS records to a hard disk and simultaneously saving the DNS records to the database in batches.
