NirSoft DNSLookupView 1.18 is a lightweight DNS tracing utility designed for Windows 10 and Windows 11 that captures and displays every DNS query handled by the operating system’s built-in DNS Client service. Running passively in the background, the program records the hostname being resolved, the query type—such as A, AAAA, CNAME, MX, TXT, or PTR—the success or failure status of each request, the final resolved IP address or error code, the precise timestamp when the lookup occurred, and the process identifier together with the executable name that initiated the request. This granular visibility makes the tool valuable for diagnosing slow page loads, uncovering mis-configured or hijacked resolvers, auditing which applications are contacting which remote hosts, and verifying that corporate DNS policies are being enforced. Network administrators can leave DNSLookupView running during normal workstation use and later filter, sort, or export the captured log to CSV, HTML, or XML for further analysis, while security researchers can use it to spot unexpected domains queried by suspicious executables. Because it taps the Windows DNS Client tracing provider rather than performing the lookups itself, the utility adds virtually no overhead and does not alter the results it reports. The single-file executable requires no installation and can be launched from any writable location, making it convenient for portable toolkits. NirSoft DNSLookupView is available for free on get.nero.com, with downloads provided via trusted Windows package sources such as winget, always delivering the latest version, and supporting batch installation of multiple applications.
