🌐 DNS Lookup Tool
Check DNS records for any domain including A, AAAA, MX, CNAME, NS, TXT, and SOA records. Verify DNS configuration and troubleshoot domain issues.
📖 DNS Record Types Explained
- A Record: Maps domain to IPv4 address
- AAAA Record: Maps domain to IPv6 address
- MX Record: Mail server addresses for email delivery
- CNAME Record: Alias pointing to another domain
- NS Record: Nameservers responsible for the domain
- TXT Record: Text information, often for verification
- SOA Record: Start of Authority with zone information
📋 How to Use the DNS Lookup Tool
- Enter a domain name such as example.com.
- Select the record types you want: A, AAAA, MX, CNAME, NS, TXT or SOA.
- Select Lookup DNS Records and read the results for each type.
🎯 When to Use It
- Checking that a domain points at the right server after a hosting move.
- Confirming MX records before setting up email.
- Looking up TXT records for SPF, DKIM or domain verification.
- Finding the authoritative name servers for a domain.
💡 Tips & Common Pitfalls
- After changing DNS, results can differ for a while because of caching and TTL. Allow time for propagation.
- A CNAME cannot sit at the root of a domain alongside other records, so root domains normally use A or AAAA.
- If you see no records, check the spelling and that you asked for a type that exists for that name.
- Several MX records are normal. The lowest priority number is tried first.
❓ Frequently Asked Questions
What is a DNS lookup?
DNS lookup retrieves Domain Name System records that map domain names to IP addresses and other information. It's how browsers find websites.
Why check DNS records?
Check DNS to verify domain configuration, troubleshoot connection issues, confirm email setup (MX records), and ensure nameservers are correct.
How long does DNS propagation take?
DNS changes typically propagate within 24-48 hours, though some updates appear within minutes. TTL (Time To Live) values affect propagation speed.
What if no records are found?
If no records appear, the domain may not be registered, DNS isn't configured, or you may have a typo. Verify the domain name and try again.
