About the WHOIS Domain Lookup
Every registered domain has a public registration record: the registrar it was bought through, when it was created and last updated, when it expires, its status locks and its nameservers. Owner contact details are usually hidden by privacy protection today.
Nuqti finds the official registry for the domain's extension and reads the record directly (modern RDAP first, classic WHOIS as fallback), then turns the dates into a clear age and an expiry countdown.
