Domain tools
Two lookups, free, with no account and no upsell. Both run on the server because neither upstream can be called from a browser, and both show what the extension costs beside the answer — which is the half every other lookup tool leaves out.
WHOIS lookup
Who a domain is registered with, when it was registered, when it expires, and which status codes are set on it. Read from the registry over RDAP.
DNS lookup
A, AAAA, CNAME, MX, NS, TXT, SOA and CAA records as they resolve right now — all eight in one query — each with the TTL that decides how long the old answer stays cached.
What these tools do not do
- They do not show a registrant's name or address. Registries redact those under ICANN policy and European data protection law, and any tool claiming otherwise is serving a stale cache or a paid database.
- They do not tell you a domain is available to buy. A registry with no record means no record — reserved names, premium pricing and registry policy are invisible to a lookup.
- They store nothing. A lookup is passed to the registry or the resolver and the answer is rendered; there is no account and no history.
