Abstract:
In various embodiments, a user or subscriber of a domain name system (DNS) service that provides various DNS resolution options or features, such as misspelling redirection, parental filters, domain blocking, or phishing protection through the DNS process, can influence how requests for domain name (DNS) information are handled on a per-request basis. The user or subscriber may configure the DNS client software of their personal computer or configure their broadband router to provide control information to a DNS server with DNS resolution options that enables the DNS server to resolve DNS queries with the DNS resolution options on a per-request basis. As a result, the user can mitigate exposure to pop-ups, pop-unders, banner ads, fraudulent offers, malware, viruses, or the like, from websites using the domain name system.
