DNS Lookup
The DNS Lookup Online tool lets you query in real time
all DNS records for any internet domain, including A, MX, NS, TXT, CNAME, SOA, SPF, DKIM, and DMARC.
It's a professional, free utility that requires no registration, ideal for system administrators, support technicians, web developers, and businesses that want to verify their domain configuration or troubleshoot email and DNS propagation issues.
With this tool, you can quickly and reliably analyze a website's DNS infrastructure
from any device. It detects configuration errors, validates SPF or DKIM records
for email authentication, and checks if your domain is correctly propagated across the internet.
The entire process is done from your browser, without installing software or sharing personal data—a secure, modern, and practical option for your web diagnostics and maintenance tasks.
