IP Messenger 5.6.17

IP Messenger 是一款專為區域網路（LAN）設計的即時通訊工具，採用彈出式視窗介面，讓同一網段內的電腦能直接互傳訊息與檔案。它最大的特色是不需要架設伺服器，只要透過 TCP/IP（UDP）協定就能運作，並具備快速檔案傳輸、圖片嵌入、桌面截圖與繪圖功能，同時提供 RSA 與 AES 加密，確保傳輸安全。這款軟體長期維護，更新頻繁，在同類工具中屬於熱門選擇，使用者評價普遍不錯。

適合需要在辦公室、學校或家庭等區域網路內快速溝通的場合，例如傳送檔案、即時討論，或需要不依賴網際網路的內部通訊。相較於 Yahoo! Messenger 或 WhatsApp 等需要網際網路與伺服器的服務，IP Messenger 完全依賴區域網路，因此更輕量且不受外部網路影響，但功能也相對單純。它提供 Windows 與 macOS 版本，免費使用，不過介面僅有英文，對於不熟悉英文的使用者可能需要適應。若你的需求僅限於內部網路溝通，這會是相當實用的選擇。
