  • Patent number: 10432584
    Abstract: In one embodiment, a DNS service provider determines that a domain name being configured by a user is a lame delegated domain name and manages the configuration of the domain name accordingly. In operation, when a user of the DNS service provider attempts to provide configuration information for a domain name, the DNS service provider determines whether the domain name is lame delegated to the DNS service provider. If the domain name is lame delegated, then, to avoid passing control of the domain name to a nefarious entity, the DNS service provider performs a verification process to determine whether the user is the rightful owner of the domain name. The user is allowed to configure the domain name within the DNS service provider when the user is the rightful owner of the domain name.

  • Patent number: 10084746
    Abstract: The present disclosure provides systems, methods, and products for high performance implementation of traffic management rules. In various embodiments, traffic management rules, such as DNS traffic management rules, are functionally expressed as rows in one or more lookup tables that are deployed to DNS resolution servers. The DNS resolution server uses the domain name, resource record type, traffic management rule types, and/or traffic management variable values to search for or look up an answer, from among multiple answers corresponding to the domain name and resource record type that meets the traffic management criteria. This look up is done without executing conventional traffic management code or scripts.

  • Patent number: 8935430
    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.
