What is My IP

This tool allows you to identify your public IP address as seen by the internet. This is useful for troubleshooting network connectivity, configuring firewalls, or setting up remote access.

How to use:
  1. Navigate to the What is My IP page.
  2. Your current IP (IPv4 or IPv6) will be displayed immediately.
  3. Below the IP, you will see your detected country based on our local database.

Note: If you are using a VPN or Proxy, the tool will show the IP address of the VPN/Proxy server, not your home network.

DNS & PTR Lookup

The DNS Lookup tool performs both Forward DNS lookups (domain to IP/MX/TXT records) and Reverse PTR lookups (IP address to hostname) with Forward-Confirmed Reverse DNS (FCrDNS) verification.

How to use:
  1. Go to the DNS Lookup page.
  2. Enter a domain name (e.g., google.com) for Forward records, OR an IP address (e.g., 209.85.216.42) for Reverse PTR resolution.
  3. Click "Lookup DNS / PTR".
Records & Modes Explained:
  • Forward DNS Mode: Retrieves A, AAAA, MX, TXT, NS, and CNAME records for hostnames.
  • Reverse PTR Mode: Converts IPv4 or IPv6 addresses into .in-addr.arpa / .ip6.arpa pointers to determine the server's PTR hostname.
  • FCrDNS Verification: Validates if the PTR hostname points back to the originating IP address to verify server authenticity.

Unix Timestamp Converter

The Unix Timestamp tool allows you to convert between seconds since the Unix Epoch (January 1, 1970) and human-readable date formats.

How to use:
  1. Navigate to the Unix Timestamp page.
  2. To convert Unix to Human: Enter the numeric timestamp in the left column. The conversion happens in real-time.
  3. To convert Human to Unix: Use the date picker in the right column to select a specific date and time.

The page also features a real-time clock showing the current global Unix epoch time.

HTTP Header Checker

The HTTP Header Checker tool allows you to inspect the metadata (headers) sent by a web server when you request a URL.

How to use:
  1. Navigate to the HTTP Headers page.
  2. Enter a full URL (including https://) into the input field.
  3. Click "Check Headers" to view the response.

This is useful for verifying security headers like Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), or checking the Cache-Control settings of a resource.

Email Header Analyzer

The Email Header Analyzer processes raw RFC 5322 headers 100% inside your browser DOM. It calculates relay hop delays, verifies SPF/DKIM/DMARC domain alignment, and detects latency bottlenecks with absolute data privacy.

Key Features:
  • Zero-Server Privacy: Header text is never uploaded to any server or recorded in logs.
  • DMARC Domain Alignment: Automatically validates whether the Header From domain matches the SPF Return-Path or DKIM d= domain.
  • Latency Bottleneck Alerts: Flags relay hops with delays exceeding 5 minutes or clock skew anomalies.
  • Sanitized IT Ticket Generator: Generates markdown diagnostic reports with optional IP and email redaction.

How to Extract Email Headers (Top 5 Providers)

  1. Open the email message in Gmail.
  2. Click the Three Vertical Dots (⋮ More options) next to the Reply arrow in the top-right corner of the email frame.

  4. In the new tab that opens, click "Copy to clipboard" or highlight and copy all text above the message body.

Outlook on the Web (Outlook.com / Office 365):
  1. Open the email message.
  2. Click the Three Horizontal Dots (... More actions) in the message header toolbar.
  3. Select View → View message details.
  4. Copy all text in the pop-up window.
Outlook Desktop App (Windows / macOS):
  1. Double-click the email to open it in a standalone window.
  2. Click File → Info → Properties.
  3. Highlight and copy all text inside the Internet headers box at the bottom.

  1. Open or select the email in Apple Mail.
  2. Click View in the macOS menu bar at the top of the screen.

  4. Highlight and copy the full text displayed in the source window.

  1. Open the email message in Yahoo! Mail.
  2. Click the "More" button (three horizontal dots ...) located above the message pane.
  3. Click "View raw message".
  4. Highlight and copy all header text from the raw tab.

  1. Select the email in Thunderbird's message list.
  2. Click View in the top menu bar (or press Ctrl + U on Windows/Linux or Cmd + U on macOS).
  3. Select Message Source.
  4. Copy all header text down to the first blank line.

Developer APIs

We provide lightweight endpoints for automated systems and CLI users.

  • Timestamp: /time/timestamp.php - Returns a JSON object with the current Unix epoch time.
  • IP Lite: /ip_lite.php - A plain-text endpoint that returns only your IP address, ideal for curl or wget.

Privacy & Security

HBCOM Tools is built with security and privacy as a priority.

  • Data Privacy: We do not log the results of your searches or lookups. Our IP database is local, meaning your IP is checked against our own server, not a third-party API.
  • Network Security: Our tools include protections (like SSRF filtering) to prevent unauthorized access to private or internal networks.
  • Abuse Protection: All tools are rate-limited to ensure availability for all users.
