See every record returned with type, value, and TTL in clean readable format
📋 DNS Record Types We Check
| 🅰️ A Record | Maps domain to IPv4 address — the most fundamental DNS record |
| 🅰️🔢 AAAA Record | Maps domain to IPv6 address — the next-generation internet protocol |
| 📧 MX Record | Mail exchange — tells email servers where to deliver mail for the domain |
| 📝 TXT Record | Text records — SPF policies, DKIM keys, DMARC, domain verification tokens |
| 🖧 NS Record | Nameserver records — which servers are authoritative for the domain |
| 🔄 CNAME Record | Canonical name — aliases one domain to another (e.g., www → root domain) |
| ⚙️ SOA Record | Start of Authority — zone metadata: primary NS, admin email, serial, refresh/retry timers |
🔧 When to Use a DNS Lookup Tool
- 🔄 DNS Migration — After switching hosting or nameservers, verify your records are pointing to the right place
- 🐛 Troubleshooting — If your website or email isn't working, check DNS is correctly configured first
- 🛡️ Security Audits — Verify SPF/DKIM/DMARC records are present and correctly formatted
- 📊 Domain Research — See email providers, hosting infrastructure, and CDN setup behind any domain
- 🌍 Propagation Check — Combine with our DNS Propagation tool to see records from 15 global locations
⚡ Pro Tip: Check DNS Globally
Our free DNS lookup is great for checking what your local resolver sees. But DNS can take 24–48 hours to propagate worldwide. Use our DNS Propagation Checker to query 15 global resolvers and see exactly where your changes have taken effect — and where they haven't yet.
❓ Frequently Asked Questions
What is a DNS lookup?
A DNS lookup translates a human-readable domain name (like example.com) into machine-readable IP addresses and other configuration data. DNS is the phonebook of the internet — every time you visit a website or send an email, a DNS lookup happens behind the scenes. Our tool shows you exactly what DNS records are published for any domain.
What DNS record types can this tool check?
Our lookup supports A, AAAA, MX, TXT, NS, CNAME, and SOA records. You can query a single record type or use "All Records" to see everything at once. This covers 99% of what you'd ever need to check — website IPs, mail servers, SPF/DKIM/DMARC policies, nameserver configuration, and zone metadata.
Is the DNS data live or cached?
Live! Our tool queries DNS in real time every time you look up a domain. You're seeing exactly what the authoritative nameservers are returning right now — not cached or stale data from hours ago. This is essential when you've just made DNS changes and need to verify them immediately.
How do I check where my email is hosted?
Run a DNS lookup with record type MX on your domain. The MX records show exactly which mail servers handle incoming email and their priority order. Then use our Email Checker to run a complete health audit including SPF, DKIM, DMARC, and blacklist status.
Why don't my DNS changes show up yet?
DNS propagation takes time — changes can take anywhere from a few minutes to 48 hours depending on your TTL (Time To Live) settings. Use our DNS Propagation Checker to query 15 global resolvers and see where your changes have taken effect. If your TTL was set high (e.g., 86400 seconds = 24 hours), that's how long old records will be cached.
Is it really free? No limits?
Yes, completely free. No signup, no credit card, no hidden limits. Check as many domains as you need. If you need programmatic access or bulk lookups, check out our API documentation and Pro plans.
