Lookups
3 tools
Look up the public records behind a domain or address. Query the DNS records that route a domain (A, MX, TXT and more), find the location and network owner behind an IP address, and read the WHOIS registration — who registered a domain and when it expires. These query live public databases, so unlike most tools here the domain or address you enter is sent out to be resolved.

Frequently asked questions
What is the difference between a DNS lookup and a WHOIS lookup?
They answer different questions. A DNS lookup returns the technical records that make a domain work — which server it points to (A), where its email goes (MX), verification records (TXT) and so on. A WHOIS lookup returns the registration details — who registered the domain, through which registrar, and the creation and expiry dates. Use DNS to see how a domain is wired, WHOIS to see who owns it and for how long.
Where does the data come from, and is it public?
From the same public infrastructure the internet itself relies on: DNS resolvers for records, regional registries for IP ownership, and registrar WHOIS servers for domain registration. It is all public information by design — these tools just query it and present it readably. Note that many domains now use privacy services that mask the registrant's personal details in WHOIS.
Why do these tools contact a server when others here do not?
Because the answer only exists out on the network. A DNS, IP or WHOIS record is not something that can be computed on your device — it has to be fetched from the infrastructure that holds it, so the domain or address you enter is sent to resolve the query. Most other tools on the site compute locally and send nothing; these are the exception by nature.
