Introduction

The Lookup IP to DNS Tool is a C# utility designed to resolve IP addresses to their corresponding DNS hostnames asynchronously. This tool is built using asynchronous programming techniques to provide efficient and non-blocking IP-to-DNS resolution.

Main GUI

Features

Overall:

  • Asynchronous IP-to-DNS resolution for improved performance and responsiveness.
  • Simple and easy-to-use.
  • Supports both IPv4 and IPv6 addresses.
  • Error handling for invalid or unresolved IP addresses.

List:

  • DNS Lookup Functionality: The tool provides the ability to perform DNS lookups on IP addresses. It can resolve IP addresses to their corresponding domain names.

  • User Interface: The tool includes a user-friendly graphical interface. It uses dialog boxes and message boxes to provide feedback to the user.

  • Input Validation: The tool validates the input IP addresses to ensure they are in the correct format. It identifies and reports invalid IP addresses to the user.

  • Backup Result Display: The tool displays the results of DNS lookups in a DataGridView for easy reference. It supports dynamic column sizing and formatting for better visibility.

  • Backup Export to CSV: Users can export the backup results to a CSV file for further analysis. It provides an option to select the destination path for the exported CSV file.

  • Error Handling and Reporting: The tool handles errors gracefully and provides informative error messages to the user. It distinguishes between different types of errors, such as host non-existence.

  • Cancellation Support: Users can cancel the DNS lookup task if it's in progress. The tool supports the cancellation of the operation and informs the user about the cancellation status.

  • Ready Status and Version Information: The tool displays a "Ready" status in the form status bar. It includes the version number in the title to indicate the tool's version.

  • Thread-Safe Processing: The tool employs thread-safe techniques to handle multiple IP addresses concurrently. It prevents duplicates and manages parallel DNS lookups.
