DNS Lookup

Perform instant DNS lookups with our free online DNS Lookup tool. Query any domain name to retrieve its DNS records including A, AAAA, CNAME, MX, NS, TXT, SOA, and SRV records. This essential network diagnostic tool helps developers troubleshoot DNS configurations, verify domain settings, check email server records, and debug connectivity issues. Whether you are setting up a new domain, migrating servers, configuring email, or investigating a DNS-related problem, this tool provides comprehensive record information in a clean, readable format. No installation required — just enter a domain name and click lookup.

What Is

The DNS Lookup tool queries Domain Name System records for any specified domain, displaying the results in an organized, human-readable format. It supports querying over 15 DNS record types: A (IPv4 address), AAAA (IPv6 address), CNAME (canonical name), MX (mail exchange), NS (name server), TXT (text records including SPF, DKIM, DMARC), SOA (start of authority), SRV (service locator), PTR (reverse DNS), CAA (certification authority authorization), and more. The tool queries authoritative DNS servers directly to ensure accurate, up-to-date results rather than cached records. Each record section shows TTL values, priority where applicable, and the full record data. This is invaluable for diagnosing email delivery problems, verifying SSL certificate configurations, checking CDN setups, and understanding your domain's complete DNS infrastructure.

How to Use

  1. Open the DNS Lookup tool in your browser — no installation or registration needed.
  2. Enter the domain name you want to look up (e.g., example.com) in the input field.
  3. Optionally select specific record types to query, or leave All selected to retrieve every available record.
  4. Click the Lookup button — the tool will query DNS servers and display results.
  5. Review the organized results showing each record type with its values, TTL, and priority.
  6. Copy any record value for use in troubleshooting or documentation.

Examples

Input: Domain: google.com, Type: A

Process: Query DNS resolver → Request A record → Return IPv4 address(es)

Result: 142.250.80.46 (TTL: 300s)

Input: Domain: google.com, Type: MX

Process: Query MX records → Sort by priority → List mail servers

Result: smtp.google.com (priority: 10)

Input: Domain: github.com, Type: CNAME

Process: Follow CNAME chain → Resolve alias → Final target

Result: github.com → No CNAME (direct A record)

Frequently Asked Questions

Is the DNS Lookup tool free?

Yes, this tool is completely free to use with unlimited queries, no account required, and no rate limits. You can perform as many DNS lookups as needed for personal, commercial, and educational purposes without any charges or restrictions.

How accurate are the DNS results?

The tool queries authoritative DNS servers to provide the most current records available. Results reflect the domain's current DNS configuration at the time of the lookup. Note that DNS propagation changes can take up to 48 hours to be visible globally, so recent changes may not yet appear.

What DNS record types can I query?

You can query A, AAAA, CNAME, MX, NS, TXT, SOA, SRV, PTR, CAA, DNSKEY, DS, NAPTR, and TLSA records. Select All to retrieve every available record type, or choose specific types to focus on particular aspects of the domain's DNS configuration.

Can I lookup DNS for any domain?

Yes, you can look up any public domain name. Private domains behind firewalls or internal network domains may not be accessible. The tool queries from a public internet perspective, similar to how any external visitor would resolve your domain's DNS.

Why do I need to check DNS records?

DNS lookups are essential for troubleshooting website connectivity issues, verifying email server configurations (MX records), checking SSL/TLS settings, validating domain ownership (TXT records), diagnosing CDN problems, and ensuring proper DNS configuration after migrations or changes.

Is my lookup activity logged or tracked?

Minimal logging is used for service reliability and abuse prevention, but the actual domain queries and results are not stored long-term or shared. Your lookup activity is treated with privacy in mind — we do not build profiles from your queries.
