Look up A, MX, TXT and other DNS records.
Pick a record type and resolver, then query what that resolver has on file. Compare answers across regions to debug propagation and geo-routing.

About this DNS lookup tool
This free online DNS lookup (nslookup / dig alternative in the browser) queries live DNS records for any domain, IP, or full URL. Check A, AAAA, CNAME, MX, NS, TXT, and SOA against Cloudflare, Google, Quad9, ControlD, OpenDNS, or the system resolver — useful for DNS propagation checks, MX verification, SPF/DKIM TXT records, and resolution debugging.
Different resolvers and regions can return different answers during propagation. Pin Nearest, US, EU, or Asia to compare how the public internet sees your zone from multiple vantage points without installing dig.
Common use cases
- Confirm A/AAAA records after a DNS cutover
- Verify MX and TXT (SPF, DKIM, DMARC) for email deliverability
- Compare answers from Google vs Cloudflare vs Quad9
- Debug CNAME chains and unexpected SOA/NS changes

DNS lookup FAQ
Is this the same as dig or nslookup?
It covers the same common record types (A/AAAA/MX/TXT/NS/SOA/CNAME) via public resolvers in your browser. It is not a full dig replacement for every flag or zone transfer.
How do I check DNS propagation?
Query the same domain with different resolvers and regions. If Google and Cloudflare still disagree after a TTL window, propagation or caching may still be in progress.
Can I look up MX and TXT for email?
Yes. Select MX or TXT (or query multiple types) to verify mail routing and SPF/DKIM/DMARC-related TXT records.
Why do resolvers disagree?
Caches, TTLs, anycast routing, and partial propagation all cause temporary differences. Re-check after the TTL and compare multiple resolvers.
