Short answer

How can I find out who owns a domain or what else is on an IP?

Your AI uses WHOIS lookups to pull contact details for specific domains and scans IP addresses to list all websites hosted on them. You get a clear map of ownership and hosting footprints. This breakdown shows you how to pull that data.

The outcomes

What you get from these lookups

The AI turns raw network data into organized intelligence.

OWNERSHIP

Domain contact details

The AI pulls registration info and contact points for a specific domain. You'll see who is officially listed as the owner.

HOSTING

IP footprint mapping

Your agent identifies every website currently sitting on a single IP address. This reveals shared hosting setups and hidden neighbors.

ANALYSIS

Connection patterns

The AI connects the dots between different domains and their shared infrastructure. You can see how different sites relate to each other.

HUMAN

Manual verification

You must manually verify the accuracy of WHOIS data since some owners use privacy proxies. The AI provides the data, but you make the final call.

The workflow

What your AI does when the request arrives.

The AI acts as your interface to the global WHOIS and IP databases.

  1. Identify the owner

    The AI queries the registration database to find the person or entity behind a domain.

    get_domain_contacts

  2. Map the IP

    The agent scans the target IP to find all other domains pointing to that same address.

    lookup_hosted_domains

  3. Organize findings

    The AI cleans up the raw registry text into a readable list of names and emails.

    get_domain_contacts

  4. Cross-reference data

    The agent compares the contact info against the hosted domain list to find patterns.

    lookup_hosted_domains

FAQ

How this task behaves.

  • 01

    Can the AI change the domain ownership info?

    No. The AI can only read existing registration data. It has no permission to modify WHOIS records.

  • 02

    Will it find domains hidden by privacy protection?

    No. If an owner uses a privacy proxy, the AI will only see the proxy service's information, not the real person.

  • 03

    Can I use this to find the physical location of a server?

    The AI can identify the IP and the hosted domains, but it does not provide precise GPS coordinates for hardware.

  • 04

    Does the AI need me to log into WHOIS sites?

    No. Once you connect the MCP, the AI handles the data retrieval directly.

  • 05

    Can the AI delete any data it finds?

    No. The tools are read-only. The AI cannot delete, edit, or remove any domain or hosting records.
