Resolve any domain's DNS records instantly. DNS lookup returns A, AAAA, CNAME, MX, NS, and other record types with full response details including TTLs and authoritative server information.
Fast, Accurate DNS Resolution
DNS lookup queries authoritative nameservers directly, showing exactly what records exist for any domain. No caching delays, no resolver filtering - just the actual DNS configuration.
Every query returns:
- Record values - IP addresses, hostnames, or text content
- TTL (Time to Live) - How long resolvers should cache the record
- Record class - Almost always IN (Internet)
- Response flags - Authoritative answer status and other metadata
Query Any Record Type
A records - IPv4 addresses where the domain resolves
AAAA records - IPv6 addresses for the domain
CNAME records - Canonical name aliases pointing to other hostnames
MX records - Mail servers with priority values
NS records - Authoritative nameservers for the domain
SOA records - Zone authority and serial number information
Practical DNS Debugging
DNS problems cause mysterious failures. Sites become unreachable, email bounces, SSL certificates fail validation. DNS lookup reveals the actual records resolvers see.
Propagation checking - After DNS changes, query multiple resolvers to verify updates have propagated. Different resolvers may cache old records until TTL expires.
Record verification - Confirm MX records point to correct mail servers and A records match your hosting.
CNAME chain tracing - Follow CNAME aliases to their final destination. Deep chains add latency and create failure points.
