What DNS Lookup Shows
DNS lookup shows the records a domain publishes, including A, AAAA, CNAME, MX, TXT, and NS entries used for websites, email, verification, and routing.
Records to Check During Setup
Check A or CNAME records for hosting, MX for email delivery, TXT for SPF, DKIM, DMARC or verification, and NS records for authoritative nameservers.
DNS Changes Can Take Time
After editing DNS, different networks may see old and new records for a while. Recheck after propagation, especially before changing mail, CDN, or production hosting.
About This Tool
DNS Lookup queries the domain name system for any record type associated with a domain: A, AAAA, MX, TXT, CNAME, NS, and more. It shows the current live DNS records without any caching layer, making it useful for verifying propagation after changes.
When to Use It
Use this after updating a DNS record to confirm the change has propagated, when diagnosing email delivery issues by checking MX and SPF records, or when verifying that a domain is pointing to the correct server.
How to Use
- Enter the domain name you want to query.
- Select the record type: A, MX, TXT, CNAME, or NS.
- Click Look Up to retrieve the current records.
- Review the results including TTL values and record data.
Frequently Asked Questions
Why are my DNS changes not showing yet?
DNS changes take time to propagate because resolvers cache records until the TTL expires. Low TTL values (300 seconds) propagate faster than high ones (86400 seconds).
How do I verify my SPF record is published?
Look up the TXT records for your domain. Your SPF record starts with v=spf1 and lists the mail servers authorised to send on your behalf.
What is the difference between an A record and a CNAME?
An A record maps a hostname to an IP address. A CNAME maps a hostname to another hostname, which is then resolved to an IP.
