DNS Lookup

The Comprehensive Online DNS Lookup Tool for Webmasters

DNS (Domain Name System) is the phonebook of the internet. It translates human-friendly domain names into machine-readable IP addresses. When you update your website's hosting, email service, or security settings, you need to verify that your DNS records are correct. Our free online DNS lookup tool allows you to check A, MX, CNAME, TXT, and NS records instantly, ensuring your site remains accessible and secure.

How to Perform a DNS Lookup Online

1. Enter the Domain: Type the domain name you want to investigate. No need to include `http://` or `www`.
2. Select Record Type: Choose the specific type of record you want to check (e.g., MX for email, A for IP addresses).
3. Start the Lookup: Click the "Lookup DNS" button. Our tool queries high-performance global DNS servers for real-time data.
4. Analyze the Results: Within seconds, you'll see a table showing the record type, TTL (Time to Live), and the actual value or target of the record.

Key DNS Records Explained

• A Record: Maps a domain name to an IPv4 address.
• AAAA Record: Maps a domain name to an IPv6 address.
• MX Record: Mail Exchange record, used to direct email to the correct mail server.
• CNAME: Canonical Name, used to point one domain or subdomain to another.
• TXT: Text records, often used for verification (like Google Search Console) and security (SPF, DKIM).
• NS: Name Server records, indicating which servers are authoritative for the domain.
