DNS Lookup
FreeLook up DNS records (A, AAAA, MX, TXT, CNAME) for any domain
About DNS Lookup
When a domain won't resolve, mail bounces, or a new record just won't take effect, the first question is always the same: what does DNS actually return right now? DNS Lookup queries a domain's records — A, AAAA, MX, TXT, and CNAME — and shows you the live answers, so you can confirm what's published instead of trusting a cached guess.
Enter a domain and the tool performs the lookup and returns the records grouped by type, straight to your browser. It is free, needs no signup, and responds in seconds. Use it to verify a record after editing your zone, to check mail routing, or to confirm a TXT record for domain or sender verification is in place.
Common uses
- Verify an A or AAAA record points to the right server after a deploy or migration
- Check MX records when email isn't being delivered to a domain
- Confirm a TXT record for SPF, DKIM, or domain verification has propagated
- Trace a CNAME chain to see where a subdomain ultimately points

FAQ
Which record types can I look up?
A, AAAA, MX, TXT, and CNAME records for any public domain.
Why don't I see a record I just added?
DNS changes take time to propagate and resolvers cache results. If you recently edited your zone, wait for the TTL to expire and check again.
Does it query my local DNS or a public resolver?
It resolves against public DNS, so results reflect what the wider internet sees rather than any local override on your machine.
Can I use DNS Lookup on mobile?
Yes — ToolHub is fully responsive and works on iPhone, Android, tablets and all modern browsers. No app install needed.
