About the DNS Lookup
This DNS lookup tool queries the records for any domain name and shows the results for the common types: A and AAAA addresses, MX mail servers, TXT records, NS nameservers, CNAME aliases and the SOA zone record. It is a fast way to inspect how a domain is configured without reaching for dig or nslookup on the command line.
The query runs server-side against public resolvers such as Cloudflare (1.1.1.1) and Google (8.8.8.8), so you see authoritative public DNS rather than your local cache. Use it to verify a new record has propagated, debug mail delivery via MX and TXT, confirm nameserver delegation, or trace a CNAME chain.
How to use it
- Enter the domain name you want to inspect, without http:// or a path.
- Submit to fetch A, AAAA, MX, TXT, NS, CNAME and SOA records.
- Review each record type and its values in the results.
- Compare against your expected configuration to spot mistakes.
- Re-run after a change to confirm the new record is visible publicly.
Examples
- Look up example.com and see its A record 93.184.216.34 plus the NS records for its nameservers.
- Check MX records to confirm mail routes to your provider, e.g. 10 mail.example.com.
- Inspect TXT records to find an SPF or domain-verification string.
- Resolve www.example.com and find a CNAME pointing to a CDN hostname.
Frequently asked questions
What is a DNS lookup?
It is the process of asking the Domain Name System for the records attached to a domain, such as the IP address (A/AAAA) or mail servers (MX). This tool performs that query and shows the results.
Which DNS records does this tool resolve?
It returns A, AAAA, MX, TXT, NS, CNAME and SOA records. These cover addressing, mail routing, text metadata, delegation and zone configuration.
How long does DNS propagation take?
Changes can take from a few minutes up to 24-48 hours, depending on the record's TTL and downstream caches. Querying public resolvers, as this tool does, shows the value they currently hold.
What resolvers does the lookup use?
The query runs on our server against public resolvers like 1.1.1.1 and 8.8.8.8, so results reflect public DNS rather than your device's local cache.
What is the difference between an A and a CNAME record?
An A record maps a name directly to an IPv4 address, while a CNAME points one name to another name as an alias. A CNAME is then resolved further to reach an address.
Can I look up any domain?
Yes, you can query any registered domain's public records. The tool only reads published DNS data and does not require ownership of the domain.
