Free DNS Lookup
Resolve every common DNS record type for a domain — A, AAAA, MX, TXT, NS, CNAME and SOA — in a single query.
What is a DNS lookup?
The Domain Name System (DNS) is the internet's address book: it maps human-friendly names like example.com to the IP addresses and services behind them. A DNS lookup asks a resolver for a domain's records — where its website lives (A/AAAA), where its email goes (MX), what verification and policy strings it publishes (TXT), which nameservers are authoritative (NS), and more. This tool queries them all at once so you can debug propagation, mail delivery and misconfiguration in seconds.
Record types at a glance
- A / AAAA — the IPv4 / IPv6 address a name points to.
- MX — mail servers, in priority order.
- TXT — SPF, DKIM, DMARC and domain-verification strings.
- NS — the authoritative nameservers for the zone.
- CNAME — an alias pointing one name at another.
- SOA — the zone's serial number and refresh timers.
How to use it
- 1Enter a domain name (for example example.com).
- 2Click Resolve to query all record types at once.
- 3Review each record group — empty types are hidden.
- 4Use the MX and TXT sections to debug email and verification issues.
Frequently asked questions
What DNS record types can I look up?+
This tool resolves A (IPv4), AAAA (IPv6), MX (mail), TXT (SPF/DKIM/verification), NS (nameservers), CNAME (aliases) and SOA (zone authority) records all at once.
Why don't I see a CNAME for my root domain?+
The DNS spec doesn't allow a CNAME at the zone apex (the root domain) alongside other records, so root domains normally use A/AAAA records instead. CNAMEs are common on subdomains like www.
How long does DNS propagation take?+
Changes are bounded by the record's TTL (time to live) plus your resolver's cache. Most updates are visible within minutes to a few hours; a stale high TTL set before the change can extend that.
How do I check my SPF or DKIM record?+
SPF and DKIM live in TXT records. Run the lookup and read the TXT section — SPF starts with 'v=spf1' and DKIM records are usually on a selector subdomain like default._domainkey.yourdomain.com.
