DNS Lookup Tool
What is DNS Lookup?
DNS (Domain Name System) lookup is a fundamental internet process that translates human-readable domain names into IP addresses that computers use to communicate. When you type a website address like "google.com" into your browser, a DNS lookup occurs behind the scenes to find the corresponding IP address where the website is hosted.
Our DNS lookup tool provides a comprehensive way to query various DNS record types for any domain name. This powerful utility is essential for website administrators, developers, IT professionals, and anyone who needs to troubleshoot domain-related issues or verify DNS configurations.

Understanding Different DNS Record Types
A Record (Address Record)
The A record is the most fundamental DNS record type that maps a domain name to an IPv4 address. When someone visits your website, the A record tells their browser which server to connect to. Every domain must have at least one A record pointing to the server's IP address.
AAAA Record (IPv6 Address Record)
Similar to A records but for IPv6 addresses, AAAA records are becoming increasingly important as the internet transitions to IPv6. These records contain 128-bit IPv6 addresses and ensure your website is accessible via the newer internet protocol.
MX Record (Mail Exchange Record)
MX records specify which mail servers are responsible for handling email for your domain. They include a priority value that determines the order in which mail servers should be contacted. Proper MX record configuration is crucial for reliable email delivery.
TXT Record (Text Record)
TXT records store text-based information and are commonly used for email authentication (SPF, DKIM, DMARC), domain verification, and other administrative purposes. They're essential for preventing email spoofing and verifying domain ownership.
CNAME Record (Canonical Name Record)
CNAME records create aliases for domain names, pointing one domain to another. They're useful for creating subdomains or redirecting traffic. For example, www.example.com might have a CNAME record pointing to example.com.
NS Record (Name Server Record)
NS records identify the authoritative name servers for a domain. These servers contain the actual DNS records for the domain and are responsible for responding to DNS queries. Proper NS record configuration is essential for domain functionality.
How to Use the DNS Lookup Tool
Using our DNS lookup tool is straightforward and requires no technical expertise. Follow these simple steps to perform a DNS lookup:
- Enter the domain name you want to check in the input field (without http:// or www)

Common DNS Issues and Troubleshooting
DNS issues can cause websites to become inaccessible or emails to bounce. Our DNS lookup tool helps identify and resolve common problems:
- Domain not resolving: Check if A or AAAA records exist and point to the correct IP addresses
- Email delivery problems: Verify MX records are properly configured with correct priority values
- Subdomain issues: Ensure CNAME or A records are set up correctly for subdomains
- DNS propagation delays: Use our tool to check if changes have propagated globally
- Security concerns: Verify SPF, DKIM, and DMARC records in TXT entries
Regular DNS monitoring using our lookup tool can help prevent many of these issues before they impact your users or business operations.
