PingDD is a versatile TCP ping tool designed for Windows, enabling users to assess the reachability of specific TCP ports on remote servers. Unlike traditional ICMP ping tools, PingDD focuses on TCP connections, providing detailed information about connection handshakes. This functionality is particularly useful for network administrators and enthusiasts who need to ensure server availability and responsiveness.

In addition to its core ping capabilities, PingDD offers an option to log connection attempts to a CSV file for further analysis. This feature allows users to keep a record of their tests, making it easier to identify patterns or issues over time. The tool's straightforward interface and efficient performance make it a valuable asset for anyone involved in network diagnostics.
