When a domain name is transmitted to both the first DNS server and the second DNS server, the first DNS server and the second DNS server respectively resolve the domain name into two groups of internet protocol (IP) addresses, and the gateway device compares the two groups of IP addresses with each other to select one of the two groups of IP addresses that is identified as all IP addresses of which are safe, and allows the client computer to access websites within the first communication network via the selected group of IP addresses to prevent the client computer from phishing attacks."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Gateway device and method for using the same to prevent phishing attacks","description":"A gateway device that is in electronic connection with at least one client computer, a first domain name system (DNS) server located in a first communication network, and a second DNS server located i","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8522336","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
