DNS Lookup
Look up A, AAAA, MX, TXT, NS, CNAME and SOA records for any domain.
Try it with this example
Query example.com for A, AAAA, MX, TXT, NS, or CNAME records. Use it to verify email setup (MX) or check if DNS has propagated.
What is this tool?
DNS (Domain Name System) translates domain names like example.com into IP addresses that computers use to connect. When you type a URL, your device queries DNS to find the IP before it can load the page. DNS also stores other records: MX records for email, TXT records for verification, CNAME for aliases, and more. This DNS Lookup tool lets you query A, AAAA, MX, TXT, NS, CNAME, and SOA records for any domain. Essential for domain setup, email configuration, and troubleshooting.
Enter a domain and select the record type. A records return IPv4 addresses; AAAA returns IPv6. MX records show mail servers and their priorities—critical when configuring email. If email doesn't work, check that MX points to the right mail provider. TXT records store arbitrary text; they're used for SPF, DKIM, domain verification, and other purposes. NS records list the name servers for the domain. CNAME points one name to another; SOA contains zone authority information.
When you add or change DNS records, propagation can take minutes to 48 hours. This tool queries DNS from our server, so you see what the public internet currently resolves. If you just added a record and it doesn't show yet, wait and try again. Use it to verify that your DNS changes have propagated, or to inspect how another site is configured. Developers check DNS when debugging connectivity, SSL setup, or email delivery.
Email setup often fails because MX or TXT records are wrong. Run an MX lookup for your domain and confirm the mail servers match your provider's documentation. SPF and DKIM rely on TXT records; a lookup shows what's published. For new domains, checking A and AAAA ensures the site points to the correct server. CDN and hosting setups use CNAME; verifying them here catches misconfigurations before they cause outages.
The tool is free and requires no signup. Queries run from our servers. Use it whenever you need a quick DNS check—before launch, during migration, or when tracking down a connectivity or email issue.
