About DNS Lookup

DNS Lookup queries the Domain Name System for any record type — A, AAAA, MX, TXT, CNAME, NS, SOA, and more — for any domain name. Use it to diagnose DNS propagation issues, verify email delivery records (SPF, DKIM, DMARC), or troubleshoot domain configuration problems.

How to Use DNS Lookup

1
Enter the domain name
Type the domain you want to look up DNS records for (e.g., example.com).
2
Select the record type
Choose the DNS record type to query: A, AAAA, MX, TXT, CNAME, NS, or another supported type.
3
Review the results
View the DNS records returned for your query, including record values, TTL values, and any relevant annotations.

Common Use Cases

Verifying DNS propagation after updating A records to a new server
Checking MX records to diagnose email delivery problems
Validating SPF, DKIM, and DMARC TXT records for email authentication
Confirming CNAME and NS records after migrating to a new hosting provider

Frequently Asked Questions

What DNS record types can I look up?

The tool supports A (IPv4 address), AAAA (IPv6 address), MX (mail server), TXT (text records including SPF and DKIM), CNAME (canonical name), NS (nameservers), SOA (start of authority), and PTR (reverse DNS) records.

How long does DNS propagation take?

DNS changes typically propagate within a few minutes to a few hours, but full worldwide propagation can take up to 48 hours due to TTL (Time to Live) caching across global DNS resolvers.

How do I check my SPF or DMARC records?

Look up the TXT records for your domain. SPF records appear as entries starting with 'v=spf1', DKIM records are found at the selector subdomain (e.g., selector._domainkey.example.com), and DMARC records are at _dmarc.example.com.
