DNS Lookup
ServerQuery A, AAAA, MX, TXT, NS, CNAME records with TTL.
How it works
Look up a domain's DNS records from an authoritative resolver. TTL (time-to-live) tells you how long resolvers cache the answer — the higher it is, the longer changes take to take effect.
About the DNS Lookup
DNS records tell the internet where a domain's website, email and services live. This free DNS lookup tool queries A, AAAA, MX, TXT, NS, CNAME and SOA records for any domain and shows their values and TTL, so you can verify configuration and troubleshoot fast.
Queries run against live DNS resolvers.
Record types you can check
- A and AAAA — the IPv4 and IPv6 addresses a domain points to.
- MX — the mail servers that receive email for the domain.
- TXT — SPF, DKIM, verification and other text records.
- NS, CNAME and SOA — nameservers, aliases and zone details.
The record types and what they do
- A / AAAA — the IPv4 / IPv6 address a name points to.
- MX — the mail servers that receive email for the domain.
- TXT — SPF, DKIM, verification strings and more.
- NS — the authoritative nameservers.
- CNAME — an alias pointing one name at another.
Frequently asked questions
What is a DNS lookup?
A DNS lookup queries the Domain Name System to find a domain's records — such as its IP address (A), mail servers (MX) or text records (TXT).
What is TTL in a DNS record?
Time To Live is how long, in seconds, a record may be cached before resolvers re-check it. Lower TTLs propagate changes faster but mean more queries.
Why don't I see a record I expect?
It may not be configured, or a recent change may not have propagated yet. Check DNS propagation across resolvers if you just made a change.
What is TTL in a DNS record?
Time To Live is how long, in seconds, resolvers may cache the record before re-checking. Lower TTLs make changes propagate faster but generate more queries; higher TTLs are more efficient but slower to update.
