Abstract: A method for providing access to an Internet resource includes registering a surrogate nameserver to be an authoritative nameserver in a DNS network, receiving at the surrogate nameserver a DNS query, maintaining at the surrogate nameserver a cache that includes a resolution of the DNS query, and executing at the surrogate nameserver a policy code to make a determination of validity of one or more of the DNS query and the cached resolution.

Abstract: A method for providing access to an Internet resource includes receiving a DNS query including a hostname to be resolved, receiving status data, invoking a code by a name indicated by the hostname, conveying the status data to the code, receiving from the code a selection of an infrastructure, and generating a DNS response directing a resolution to the infrastructure.

Abstract: A system for surveying Internet access quality includes a nameserver, registered to be authoritative for a domain name and configured to receive a DNS query to resolve a pseudo-hostname and to extract from the pseudo-hostname an access quality indicator, and a web portal configured to transmit a data survey code to a web browser, the data survey code being configured to access a resource, to determine the access quality indicator responsively to the resource access, to generate the pseudo-hostname including the access quality indicator and the domain name, and to initiate the DNS query.

Abstract: The technology disclosed relates to refined survey of Internet infrastructures. A pattern of measurements is disclosed that can improve data collection by increasing the number of measurements per survey session according to a function described in areas that have few measurements, and decreasing the average number of measurements per session in heavily measured areas. These are new problems that arise from implementation of technology developed by these inventors and their colleagues.

Abstract: The technology disclosed relates to DNS resolution of bare domain names of the form “myexample.com”. A bare domain name is also called zone apex or naked domain. In particular, bare domains are resolved by look-up of “A” records, per the IETF standards for DNS resolution. Technology is disclosed that improves resolution of bare domains to edge servers or other devices of a content delivery network or cloud-based content provider (collectively referred to as CDNs).

Abstract: The technology disclosed relates to detection of anonymous proxies and bots making requests to a cloud based resource on the Internet, such as a web server or an App server. The technology can leverage one or more of: instrumentation of web pages that samples response times and other characteristics of communications by a requestor device over multiple network segments; lack of prior appearance of the requestor device across multiple, independently operated commercial web sites; and resolver usage by the requestor. These signals can be analyzed to score a requesting device's reputation. A location reported by a user device can be compared to a network characteristic determined location.

Abstract: The technology disclosed relates to delivering frequently updated data to computing devices that make decisions about selection of resources that might be delivered in response to a request from a user. In particular, it relates to utilizing media content delivery networks to deliver non-media data that is useful in the decision-making.
