DNS Lookup queries the Domain Name System to find records associated with a domain. It reveals how a domain is configured – what IP addresses it points to, where email is routed, and more.

What DNS record types can I check?

You can check A (IPv4), AAAA (IPv6), MX (mail), CNAME (alias), TXT (text/SPF/DKIM), NS (nameservers), SOA (authority), SRV (services), CAA (certificate authority), and PTR (reverse DNS) records.

Why do I see different results than other tools?

DNS results depend on the resolver used. This tool uses the server’s system resolver. Different geographic locations and DNS providers may cache records differently.

How do I check MX records for a domain?

Select the MX record type and enter the domain name. MX records show which mail servers handle email for the domain, along with their priority values. Lower priority numbers indicate preferred servers.

What does TTL mean in DNS?

TTL (Time-to-Live) is the number of seconds a DNS record is cached by resolvers before they query the authoritative server again. Lower TTL values mean changes propagate faster but increase DNS query load.

How do I find nameservers for a domain?

Select the NS record type and enter the domain. NS records list the authoritative nameservers responsible for the domain’s DNS zone. These are the servers that hold the master copy of all DNS records.

SSL Certificate Checker

Inspect SSL/TLS certificates. Check issuer, validity dates, subject alternative names, and certificate chain.

Blacklist Check

Check if an IP address or domain is listed on DNS-based blacklists (DNSBL). Test against Spamhaus, Barracuda, SpamCop, and more.

DNS Health Check

Run a comprehensive DNS health check on your domain. Analyze nameservers, SOA, MX, web records, and email authentication.
