About the SERPInsight DNS Records Checker
The Domain Name System (DNS) is the phonebook of the internet, translating human-readable domain names into machine-readable IP addresses.
Developed by SERPInsight, this tool queries authoritative servers directly to fetch your domain's live configuration. It allows webmasters and IT engineers to quickly verify routing, email setups, and security validations without needing terminal commands.
How it works
-
1
Input Domain
Enter your target domain name (e.g., example.com) in the field above to begin the query.
-
2
Process Request
Our system securely contacts global resolvers to fetch all propagated records (A, MX, TXT, etc.).
-
3
Review & Export
Filter the generated results by record type, verify targets, and export the zone data to CSV.
Understanding DNS Metrics
These records point your domain name to the physical IP address of your hosting server. 'A' points to IPv4 addresses, while 'AAAA' points to newer IPv6 networks.
Mail Exchanger (MX) records direct email to your domain's mail servers. They dictate how email should be routed using a priority system (lower numbers have higher priority).
TXT records provide text information to outside sources, crucial for email security (SPF, DMARC) and site verification. CNAMEs alias one domain to another.
DNS Optimization Guide
Key Concepts
- Email Deliverability: Ensuring correct SPF and DMARC text records are present prevents your emails from landing in spam.
- Site Uptime: Verifying your Nameservers (NS) are correctly assigned ensures traffic routes seamlessly to your host.
- TTL (Time To Live): This determines how long servers cache your DNS data before requesting a fresh copy. Lower TTLs are ideal during migrations.
Best Practices
- Regular Audits: Periodically check your DNS configuration to clear out old, unused CNAMEs to prevent subdomain takeover attacks.
- Verify SSL: Ensure that your A records align exactly with your SSL certificate provisioning to avoid browser warnings.
- Consolidate TXT: Avoid creating multiple SPF records. Combine all authorized mail senders into a single TXT entry to adhere to strict validation protocols.
