DNS Lookup
Look up DNS records
Frequently Asked Questions
What is a DNS lookup?
A DNS lookup translates a domain name (example.com) into an IP address (93.184.216.34) that computers use to connect. The tool queries DNS servers and returns all record types: A (IPv4), AAAA (IPv6), MX (mail), CNAME, TXT, NS, and SOA records.
How do I check DNS records for a domain?
Enter the domain name (e.g., example.com). The tool queries public DNS servers and displays all records: A records (IP addresses), MX records (mail servers), TXT records (SPF, DKIM), NS records (nameservers), and CNAME records (aliases).
What are the different DNS record types?
A: maps domain to IPv4 address. AAAA: maps to IPv6. CNAME: alias to another domain. MX: mail server with priority. TXT: text data (SPF, DKIM, verification). NS: authoritative nameservers. SOA: zone authority info. PTR: reverse DNS lookup.
How long does DNS propagation take?
DNS changes propagate in 1-48 hours, depending on TTL (Time To Live) values. Low TTL (300s): propagates in minutes. Default TTL (3600s): up to 1 hour. High TTL (86400s): up to 24 hours. The tool shows current TTL values for each record.
How do I troubleshoot DNS issues?
Check if the domain resolves: run a DNS lookup. Compare results from multiple DNS servers (Google 8.8.8.8, Cloudflare 1.1.1.1). Verify NS records point to the correct provider. Check for DNSSEC issues. The tool queries multiple servers for comparison.
