Quick DNS analysis of the domain you're viewing, with a single click to open the full report. NS Lookup is a browser extension that performs a quick analysis of the most common DNS entries for the domain you're currently viewing. Right from your toolbar, with a single click. Click the NS Lookup icon and get an instant summary of the active domain's key DNS records: - Nameservers - the authoritative servers for the domain - A / AAAA - the addresses the domain resolves to - MX - the domain's mail server records - Registrar - where the domain is registered - Health - a summary of any errors or warnings found for the domain Need more depth? A single button opens the complete NS Lookup analysis of the domain, covering glue records, SOA, TXT, mail security (SPF, DKIM, DMARC), web signals (reverse DNS / PTR, ASN), and propagation across public resolvers. No account needed. The extension reads the current domain's hostname only when you click the action and sends it to the NS Lookup API for analysis.
