  • Publication number: 20140026186
    Abstract: Systems and methods for creating a list of trustworthy resolvers in a domain name system. A computer receives a resolver profile for a resolver sending queries to a domain name server. The resolver profile is based on any, or a combination, of a top-talker status of the resolver, a normalcy of distribution of domain names queried, a continuity of distribution of query type, and a RD bit status, and information related to query traffic based on the topology of the domain name server. Resolver profiles can be compared to a trust policy to determine whether the resolver is trustworthy. Resolvers deemed trustworthy can be added to a list of trustworthy resolvers. Embodiments can detect the occurrence of a network-based attack. Embodiments can mitigate the effect of a network-based attack by responding only to queries from resolvers on the list of trustworthy resolvers.

  • Publication number: 20140006642
    Abstract: Methods and systems are disclosed for quickly providing Whois services to a new top level domain after it is provisioned in a registry. In one embodiment, domain data is received at a first system regarding a top level domain (TLD). The domain data is assigned an authoritative port of a Whois server and is provisioned in a registry database. In certain embodiments, the Whois server provides information relating to domain name registrations of the TLD in the database, according to the authoritative port. The Whois server determines that a Whois query is received at the authoritative port for the queried TLD and responds with the queried information. To the requester, the responses appear as if they are sent from a unique Whois server for each TLD, but the Whois server is actually shared among the TLDs.

  • Patent number: 8564683
    Abstract: An in-camera two-stage compression implementation is described that reduces the latency between snapshots to a fraction of that otherwise required by other systems that either process complete compression following each snapshot or that incorporate heavy, bulky, and expensive RAM hardware capable of maintaining several raw luminosity records (unprocessed file containing a digital image). In the 1st stage compression the raw luminosity record is quickly, yet partially, compressed to available RAM buffer space to allow a user to expeditiously capture a succeeding image. When the higher-priority processes, the user shooting pictures, and stage one compression subside, a 2nd stage compression, which is slower but more effective, decompresses the earlier partially-compressed images, and re-compresses them for saving in flash memory until they are distributed to a remote platform to be finally converted to the JPEG2000 format.

  • Patent number: 8527658
    Abstract: An automated method for determining domain traffic including receiving at authoritative name server a request to resolve a domain name that has n labels separated by periods. The leftmost label is the first label and the top level domain is the nth label. If the first label of the received domain name includes the string “www”, then a www hit counter and/or a www requesting server counter for the domain name are incremented. If the received domain name has only two labels, then an exact hit counter and/or an exact requesting server counter for the domain name are incremented. If the first label of the received domain name does not include the string “www” and does not have only two labels, then another hit counter and/or another requesting server counter for the domain name are incremented. A domain traffic score is calculated based upon a plurality of the counters, and calculating the domain traffic score includes applying a weighting factor to at least one of the counters.

  • Patent number: 8527309
    Abstract: A system, method, and computer-readable medium, is described that provides a probability of deletion (or renewal rate) prediction for a domain name based on a historical model of expired and renewed domain names. Domain name attribute sets are defined using domain attribute/value combinations. These sets are used to classify past expired and renewed domain names into each of the applicable sets where the domain attribute and values match the expired or renewed domain names. The percentage of renewed domain names in a set is used to predict the likelihood that a user will renew a domain name set to expire in a defined window and that matches the attribute/value combinations that make up the domain attribute set. This predicted percentage is used to target domains and deliver marketing offers to the domain contacts.

  • Patent number: 8521845
    Abstract: A method, system, and computer-readable medium are described for registering and using multilingual domain names that include characters outside the ASCII character subset supported by the DNS system. Such multilingual domain names can in some situations be registered by first being converted into appropriate ASCII-Compatible Encodings (ACEs) that represent the corresponding multilingual domain names and that use only characters within the ASCII character subset. In addition, a variety of binary variants may be generated at registration for each multilingual domain name and then used as equivalents for the multilingual domain name, such as by storing the variants in the registry as alternative domain names or by otherwise reserving the binary variants. When requests to resolve such a registered multilingual domain name into a corresponding IP address or URL are received, the stored binary variants and/or ACE information can then be used to respond in an appropriate manner.
