How to Use the DNS Lookup Tool
To perform a DNS Lookup, enter your domain name (e.g., smtk.pro) into the input field above and click "Submit." Our tool will instantly query global DNS resolvers to retrieve the active records for your domain, allowing you to verify your server settings, mail configurations, and security policies in real-time.
Functionality and Essential DNS Records
The DNS Lookup functionality is a critical diagnostic utility for managing a website’s digital infrastructure. It allows you to inspect the individual "building blocks" of your domain's configuration:
- A & AAAA Records: Verify the IPv4 (A) and IPv6 (AAAA) addresses your domain points to. This is the first check if your website is down or showing a "Server Not Found" error.
- MX Records (Mail Exchange): Identify the mail servers responsible for your domain's email. Proper MX configuration is essential to ensure your business emails are delivered and not bounced.
- CNAME (Canonical Name): Check alias records used to point subdomains (like
wwworblog) to your root domain or external services like Shopify or Zendesk. - TXT Records: Crucial for domain ownership verification (Google Search Console, Microsoft 365) and email security protocols like SPF, DKIM, and DMARC.
- NS Records (Nameservers): Confirm which DNS provider (e.g., Cloudflare, Route53, or your registrar) is currently authoritative for your domain.
