DNS Lookup Tool
Find all DNS records for a domain name including A, AAAA, CNAME, MX, NS, SOA, and TXT records.
Understanding DNS Records
A Record
Maps a domain name to an IPv4 address. Essential for directing traffic to your website.
AAAA Record
Maps a domain name to an IPv6 address. The next-generation IP addressing system.
CNAME Record
Redirects one domain to another, creating an alias for domain name resolution.
MX Record
Specifies mail servers for email delivery. Critical for proper email functionality.
TXT Record
Stores text-based information often used for verification, SPF, DKIM, and DMARC records.
NS Record
Identifies authoritative name servers for a domain. Controls where DNS records are managed.
What is DNS Lookup and Why It Matters for Your Website
DNS (Domain Name System) lookup is the process of translating human-readable domain names into machine-readable IP addresses. When you enter a website URL in your browser, a DNS lookup happens behind the scenes to locate the correct server hosting that website.
How DNS Lookup Works
The DNS lookup process involves multiple steps: First, your browser checks its cache for recently visited domains. If not found, it queries recursive DNS servers, which then communicate with authoritative name servers to find the correct IP address associated with the requested domain.

Common DNS Record Types Explained
Understanding different DNS record types is essential for proper domain management. Our DNS lookup tool supports all major record types including A records for IPv4 addresses, AAAA records for IPv6 addresses, MX records for mail servers, CNAME records for aliases, TXT records for verification purposes, and NS records that identify authoritative name servers.
Best Practices for DNS Management
To ensure optimal website performance and reliability, follow these DNS best practices: Use a reputable DNS provider, implement DNSSEC for enhanced security, set appropriate TTL values, regularly monitor your DNS records, and keep your DNS information updated when making changes to your hosting environment.
