DNS Checker

What is DNS Checker?

DNS Checker is a technical SEO and networking tool that allows you to instantly resolve and list worldwide DNS records for any domain name. By querying directly (DoH) through massive resolvers like Cloudflare 1.1.1.1 or Google Public DNS (8.8.8.8), our tool brings up your A, AAAA, CNAME, MX, TXT, NS, and SOA records in seconds. If you've moved to a new server (DNS propagation), set up mail settings, or can't access your site at all, you can verify here if the issue is DNS-related.

What are the Supported DNS Record Types?

• A Record: Shows the IPv4 address the domain points to. It is the most fundamental record.
• AAAA Record: Shows the next-generation IPv6 address the domain points to.
• CNAME (Canonical Name): Used to redirect one domain name to another (e.g., connecting www.site.com to site.com).
• MX (Mail Exchange): Determines which email servers incoming emails will be forwarded to.
• TXT Record: Adds text information to the domain. Commonly used for security and SEO verification policies like Google Search Console verification, SPF, DKIM, DMARC.
• NS (Name Server): Shows which servers host the DNS management of the domain.

The Impact of DNS Health on SEO

Search engine bots (e.g., Googlebot) must first resolve the DNS of a website to crawl it. If your DNS servers are slow to respond or connections drop due to configuration errors, Googlebot cannot reach your site, and your crawl budget is wasted. Prolonged DNS outages can even drop your site from search results. Using fast and reliable DNS (e.g., Cloudflare) directly improves TTFB (Time To First Byte), allowing pages to render sooner.

How to Use?

Enter your domain address in the search bar (example: seoaraci.com). Then select the record type you want to check and click the query button. Within seconds, all defined DNS zone information belonging to that domain will appear in a structured table.

Frequently Asked Questions (FAQ)

Question: I made a DNS redirection, but the old site still opens, why?
Answer: The propagation of DNS records to all servers worldwide (DNS Propagation) can take between 2 and 48 hours. This depends on how often your local internet provider clears its TTL cache.

Question: How is Google Search Console verified with a TXT record?
Answer: Google gives you a unique code ("google-site-verification=...") in the GSC panel. You add this code as a TXT record to your server from your domain provider's panel. You can make sure it's added by doing a TXT query in our tool.
