DNS Lookup — Resolve A, AAAA, MX, TXT Records

Resolve A, AAAA, MX, TXT, and more. Free DNS lookup tool.

The DNS Lookup tool queries DNS for a domain and returns the requested record types (A, AAAA, MX, TXT, CNAME, NS, etc.). Use it to verify records after changes, to debug "domain not found" or wrong IP, and to inspect SPF/DKIM/DMARC or other TXT-based config. Queries can be run from our server for consistent results.

Frequently Asked Questions

What record types are supported?

Typically A, AAAA, MX, TXT, CNAME, NS, SOA, PTR. Some tools support more (e.g. CAA, SRV).

Why do I see different results elsewhere?

DNS is cached and can vary by resolver and location. TTL and propagation delay affect what you see.

What is DNS propagation?

The time for a record change to spread globally. Lower TTL before changes; after, you may wait up to TTL or longer.

Can I specify a nameserver?

Some tools let you query a specific resolver or authoritative NS. Useful to compare cached vs authoritative.

How do I check SPF or DKIM?

SPF and DKIM use TXT records. Run a TXT lookup for the domain or the DKIM selector subdomain.
