Use the DNS Lookup tool to query any DNS record type — A, AAAA, MX, TXT, CNAME, NS, PTR, SOA — and understand what each record type does.

Your domain has no MX records, which means it can't receive email. Learn why MX records are essential and how to set them up correctly.

Look up A records to find the IPv4 addresses a domain resolves to. Understand what A records do, how DNS resolution works, and how to diagnose common issues.

Look up AAAA records to find IPv6 addresses for a domain. Understand dual-stack DNS, when AAAA records matter, and how to verify IPv6 connectivity.

Look up CNAME records to trace DNS aliases. Understand how CNAMEs work, their limitations, and common issues like CNAME-at-apex conflicts.

Look up NS records to see which nameservers are authoritative for a domain. Verify DNS delegation and diagnose propagation issues.
