DNS Lookup
Perform DNS lookups for any domain name using DNS-over-HTTPS (DoH). Query various DNS record types including A (IPv4), AAAA (IPv6), MX (mail exchange), TXT (text records), CNAME (canonical name), NS (name servers), and SOA (start of authority). Get detailed DNS information including TTL values, record data, and authoritative nameservers. Perfect for debugging DNS issues, verifying domain configurations, and understanding DNS records.
Frequently Asked Questions
How do I perform a DNS lookup?
Enter a domain name (e.g., jsonyaml.com) and select a record type (A, AAAA, MX, etc.). Click "Lookup" to query the DNS records. The results will show all matching records with TTL values and record data.
What DNS record types are supported?
The tool supports A (IPv4 addresses), AAAA (IPv6 addresses), MX (mail exchange), TXT (text records), CNAME (canonical names), NS (name servers), and SOA (start of authority) record types.
How does DNS-over-HTTPS work?
DNS-over-HTTPS (DoH) encrypts DNS queries using HTTPS, providing privacy and security. The tool uses Cloudflare's and Google's DoH services with automatic fallback, which are fast, reliable, and don't require authentication.
What is TTL?
TTL (Time To Live) is the number of seconds a DNS record can be cached before it needs to be refreshed. Lower TTL values mean records change more quickly, while higher values reduce DNS query load.
Can I query multiple record types at once?
Currently, you can query one record type at a time. You can perform multiple lookups to get different record types for the same domain.
