🔎 Domain Investigator

Domain Investigator retrieves publicly available RDAP registration information for a domain.

Example

SignalLab > 1

DOMAIN INVESTIGATOR

Enter domain: example.com

[*] Looking up registration data...

DOMAIN INFORMATION
--------------------------------

Domain       : example.com
Status       : Registered
Registration : YYYY-MM-DD
Expiration   : YYYY-MM-DD
Last Updated : YYYY-MM-DD
Registrar    : Example Registrar
RDAP Server  : https://...

Domain Status:
  • active

Name Servers:
  • example.ns.cloudflare.com
  • example2.ns.cloudflare.com

Information Available

  • Domain name
  • Registration date
  • Expiration date
  • Last updated date
  • Registrar
  • RDAP server
  • Domain status
  • Name servers

Only publicly available registration information is used.

📧 Disposable Inbox

The Disposable Inbox module provides a temporary mailbox for development and testing workflows.

Features

  • Generate disposable email address
  • Refresh inbox
  • View received messages
  • Delete mailbox
  • Maintain local mailbox session

Example

DISPOSABLE INBOX

Address : example123@temporary-domain.com

[1] Generate New Disposable Email
[2] Refresh Inbox
[3] Read Message
[4] Delete Mailbox
[5] Generate Another Address
[0] Back

Use disposable mailboxes only for legitimate testing and development purposes.

🌐 DNS / Host Lookup

Resolve a hostname and display its IPv4 address.

Example

SignalLab > 3

DNS / HOST LOOKUP

Enter hostname: example.com

[+] DNS lookup successful.

Host        : example.com
IPv4 #1     : 93.184.216.34
Lookup time : 25.42 ms

Useful for DNS troubleshooting, connectivity diagnostics, and development testing.

🖥️ Network Information

Displays basic information about the local system and network environment.

Example

NETWORK INFORMATION

SYSTEM

📝 Logging

SignalLab automatically records local activity in:

signallab.log

Example:

[2026-08-21 12:00:00] DNS lookup: example.com
[2026-08-21 12:01:20] Domain Investigator: example.com
[2026-08-21 12:02:10] Identity Generator: 1 synthetic identities generated.

The log file is generated automatically when SignalLab is used.

🔐 Responsible Use

SignalLab is intended for:

  • Educational purposes
  • Software development
  • Network diagnostics
  • Domain research
  • Authorized security testing
  • Local experimentation
  • Synthetic test-data generation

Only test systems, services, APIs, domains, and resources that you own or have explicit permission to test.

SignalLab should not be used to:

  • Access accounts without authorization
  • Collect private personal information
  • Bypass authentication
  • Intercept third-party verification codes
  • Disrupt services
  • Conduct unauthorized security testing

Users are responsible for complying with applicable laws, service policies, and authorization requirements.

🧪 Development

SignalLab is written in Python and is designed to remain lightweight, portable, and easy to extend.

Most modules use Python's standard library. Online features use public APIs and RDAP services where applicable.

  • Domain Investigator
  • RDAP domain lookup
  • DNS / hostname lookup
  • Network information
  • TCP connectivity testing
  • Local logging
