NS Lookup - DNS Analysis PlanetHoster מאת

NS Lookup - DNS Analysis 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, no tracking. The extension sends the current domain to the NS Lookup API for analysis only when you click the action.
