DNS Lookup
Check every DNS record for any domain in one click.
What does all this mean?
This tool checks every common DNS record type for the domain or IP you enter, then translates the result into plain English. Run it any time you suspect a website, email, or vendor change broke something.
What is DNS, and why should I care?
DNS is the internet’s address book. It translates a friendly name like example.com into the technical records that browsers, email providers, and other services need.
For small teams, the tricky part is that DNS often gets touched by several people over time: a web designer, a previous IT provider, a marketing platform, a mailbox vendor, or whoever bought the domain years ago. A quick check helps you see what the public internet sees before you start changing settings.
This tool does not replace a full review. But it answers the first practical question: “What is actually published right now, and is anything obviously broken?”
Glossary: what each record type means
A - points a domain to an IPv4 address, usually for a website.
AAAA - points a domain to an IPv6 address (the newer internet address format).
MX - tells the internet which mail servers receive email for the domain.
TXT - text settings used for verification, security, and email trust (SPF lives here).
NS - the name servers responsible for answering DNS questions for the domain.
CNAME - points one domain name to another, often for hosted tools or “www” subdomains.
SOA - confirms the domain has a registered DNS zone and shows who controls it.
CAA - restricts which certificate authorities can issue SSL certificates for the domain.
PTR - maps an IP address back to a name. Matters most for mail servers and spam checks.
