Indy officially stopped supporting Delphi 4 a long time ago. Delphi 5 is the earliest version still supported. Delphi has its own socket classes - TClientSocket and TServerSocket - which can operate in both blocking and non-blocking modes. Indy operates strictly in blocking mode only.
Without using Indy, you can get the machine's IP(s) using either the WinSock API's gethostname and gethostbyname functions, or the Win32 API's GetAdapterAddresses or related functions, and use the Win32 API IcmpSendEcho function to ping.
