About
The DNS Record Checker is a free utility that allows you to instantly investigate and retrieve various DNS (Domain Name System) records associated with a specified domain directly from your browser.
It provides essential information for infrastructure troubleshooting, such as verifying A record propagation during website migrations, checking MX records for email server setup, and validating TXT records used for spam prevention (SPF/DKIM/DMARC).
By utilizing Google's public DNS-over-HTTPS (DoH) API, this tool ensures world-class speed and accuracy when fetching the latest record data.
How to Use
Enter Domain Name
Input the domain name you wish to investigate (e.g., example.com) into the search box. Any URL schemes like http:// are automatically stripped.
Run Search
Click the "Check DNS Records" button or press Enter to initiate the lookup.
View Results
Major records like A, AAAA, MX, TXT, CNAME, and NS will instantly appear. TTL (Time To Live) values are also displayed so you can verify cache expirations.
Glossary
- DNS (Domain Name System)
- The foundational system of the internet that translates human-readable domain names (e.g., digrart.jp) into machine-readable IP addresses (e.g., 192.0.2.1) required for network communication.
- A Record
- The most basic DNS record that maps a domain name to an IPv4 address. When accessing a website, the browser refers to the A record to locate the host server.
- MX Record (Mail Exchange)
- Specifies which mail servers are responsible for accepting email messages on behalf of a domain. It includes a priority value where a lower number indicates higher preference.
- TXT Record
- Allows domain administrators to insert arbitrary text into DNS records. It is primarily used for domain ownership verification and email security protocols like SPF and DMARC.
- CNAME Record
- An alias record that maps one domain name to another (canonical) domain name. Frequently used when configuring CDNs or directing subdomains to a primary domain.
- TTL (Time To Live)
- The expiration time (in seconds) for which a DNS record is cached by resolvers and browsers. It is common practice to lower this value (e.g., to 300 seconds) prior to a server migration.
FAQ
- Q.I migrated my server, but the new IP address is not showing up.
- It can take up to 24-72 hours for DNS changes to propagate fully across the internet. Additionally, if the previous TTL (Time To Live) was set to a high value, cached data may continue to be returned until it expires.
- Q.Can I check DNS records for subdomains?
- Yes, you can. By entering a subdomain directly (e.g., sub.example.com), you can accurately retrieve the A or CNAME records specifically assigned to that subdomain.
- Q.Is my entered domain information logged or saved?
- No. This tool makes requests directly from your browser to a public DNS API (Google DoH) and does not route through our servers. Your search history and domain information are never logged, ensuring complete privacy.
- Q.Where can I verify SPF records?
- SPF (Sender Policy Framework) settings are registered as "TXT records". Check the TXT record section in the results for a string starting with v=spf1.
- Q.I received an error saying "No records found".
- The entered domain name might be incorrect, or the domain is currently not registered or resolvable by any nameserver (e.g., expired). Please double-check the spelling.
Use Cases
Website Renewals & Migrations
Use this to verify from an external perspective whether domain routing updates (like A records and CNAMEs) have been correctly applied after switching to a new server.
Email Delivery Troubleshooting
Diagnose corporate email setups by confirming MX record priorities or ensuring that missing SPF records aren't causing emails to be flagged as spam.
Ownership Verification
Check if the required TXT records are visible to external services when registering a domain with Google Search Console or other third-party tools.
