DNS Lookup

Query DNS records for any hostname.

DNS (Domain Name System) is the phonebook of the internet. It translates domain names like example.com into IP addresses that computers use to communicate. Every website visit, email sent, or API call starts with a DNS lookup.

Several record types serve different purposes: A maps to IPv4, AAAA to IPv6, MX routes email, CNAME creates aliases, TXT stores SPF/DKIM data for email security, NS points to nameservers, and SOA holds zone admin info.

This tool queries all key record types for any domain — useful for troubleshooting mail delivery, verifying DNS propagation, and diagnosing connectivity issues.
