Domain WHOIS FAQs

Question 1

Can I check multiple domains for availability at once?

Accepted Answer

Yes, Domain WHOIS features a 'bulk domain check' capability, allowing you to check the availability of up to 50 domains concurrently. This is ideal for finding available names across various TLDs or auditing a domain portfolio.

Question 2

What kind of data can I retrieve with WHOIS and RDAP lookups?

Accepted Answer

You can retrieve comprehensive domain registration details including registrar information, creation/expiration dates, nameservers, contact details (where public), and domain status flags. RDAP provides modern, structured JSON data, while WHOIS offers raw and parsed text.

Question 3

What is Domain WHOIS and what does it do?

Accepted Answer

Domain WHOIS is a powerful tool designed for gathering real-time domain intelligence. It performs WHOIS and RDAP lookups, checks domain availability (single and bulk), and retrieves TLD information using native protocols directly, providing structured data for developers and AI agents.

Question 4

How does Domain WHOIS differ from other domain lookup tools?

Accepted Answer

Unlike many tools that rely on third-party APIs or web scrapers, Domain WHOIS interacts directly via native WHOIS (TCP:43) and RDAP (HTTPS) protocols. This means zero API keys, no rate limits, and authentic data directly from registries, with built-in server databases and smart parsing.

Question 5

Is this tool suitable for AI agents or automated workflows?

Accepted Answer

Absolutely. Domain WHOIS is built as an MCP (Model Context Protocol) server, making it perfectly compatible with AI agents like Claude Code. It empowers agents to perform tasks like domain validation, competitive research, and automated infrastructure checks programmatically.
