# How to Research IP Ownership with Copilot

Copilot brings IP ownership research into your security development workflow. Look up owners of IPs in your application logs, verify that external endpoints belong to expected organizations, and generate allowlist configurations based on verified ownership data -- all without leaving your development environment.

## Setup

{"mcpServers":{"toolrouter":{"command":"npx","args":["-y","toolrouter-mcp"]}}}

## Steps

1. Add ToolRouter to Copilot MCP config
2. In Copilot Chat: "Look up the owner of this IP address"
3. Copilot returns the ISP, ASN, and organization details
4. Ask: "Check all external IPs in our config for ownership"
5. Document the ownership data for your security review

## Example Prompt

```
Look up the ownership of these IPs from our firewall logs. Identify which organizations they belong to.
```

## Tips

- Useful for auditing which external services your application communicates with
- Copilot can help build IP allowlists based on ownership verification
- Cross-reference with known service provider IP ranges
