Use our free Domain DNS Lookup tool to view DNS records like A, MX, TXT, NS, and CNAME. Great for troubleshooting, configuration, and DNS diagnostics.

Every domain name on the internet is powered by DNS — the system that translates human-readable domains into IP addresses and routes email, traffic, and security policies. 

The Domain DNS Lookup Tool lets you instantly view DNS records for any domain, giving you visibility into how it’s configured and what services it's using.

Whether you're setting up email, verifying records, or debugging configuration issues, this tool is essential for developers, sysadmins, and IT professionals.

What Are DNS Records?

DNS (Domain Name System) records define how internet traffic is directed for a domain. Common types include:

• A Record – Points a domain to an IPv4 address
• AAAA Record – Points a domain to an IPv6 address
• MX Record – Directs email to a mail server
• TXT Record – Stores SPF, DKIM, or verification text
• NS Record – Specifies authoritative name servers for the domain
• CNAME Record – Alias of one domain to another
• SOA Record – Contains domain start-of-authority information

The Domain DNS Lookup Tool lets you retrieve and inspect all these records in real time.

Why Use a Domain DNS Lookup Tool?

DNS issues are one of the most common causes of email failures, website downtime, and misrouted traffic. The Domain DNS Lookup Tool helps you:

• Verify correct DNS configuration
• Check propagation status after changes
• Troubleshoot email delivery issues (SPF, DKIM, MX)
• Inspect competitors’ DNS setups
• Ensure DNS records are pointing to the right services

It’s also ideal when launching a new site, switching hosts, or auditing security settings.

Use Cases for DNS Lookups

• Web Hosting Setup: Confirm A, CNAME, and NS records after migration
• Email Troubleshooting: Validate MX, SPF, DKIM, and DMARC records
• Domain Transfers: Ensure NS records have propagated
• CDN Configuration: Check if traffic is routing through Cloudflare, etc.
• Cybersecurity & Auditing: Monitor external DNS changes

Common DNS Troubleshooting Examples

• Website down? Check A or CNAME records.
• Email not sending? Inspect MX, SPF, and DKIM records.
• Domain still pointing to old host? Confirm NS record updates.
• Can’t verify domain with Google or Facebook? Check TXT records.

With the Domain DNS Lookup Tool, you can instantly access and verify those records — ensuring your site, email, and services are always pointing in the right direction.
