Как оперделить все IP и порты на моем компьютере?

Функции GetTcpTable, GetUdpTable.

Импорт GetTcpTable:

unit TcpTable;
interface
type
  PDWord = ^Longword;
  PMIB_TCPROW = ^TMIB_TCPROW;
  TMIB_TCPROW = record
    dwState: LongWord;
    dwLocalAddr: LongWord;
    dwLocalPort: LongWord;
    dwRemoteAddr: LongWord;
    dwRemotePort: LongWord;
  end;
  PMIB_TCPTABLE = ^TMIB_TCPTABLE;
  TMIB_TCPTABLE = record
    dwNumEntries: LongWord;
    table: array[0..0] of TMIB_TCPROW;
  end;
function GetTcpTable(var TcpTable: PMIB_TCPTABLE; var Size: PDWord; bOrder: Boolean): LongWord; stdcall
implementation
function GetTcpTable; external 'Iphlpapi.dll' name 'GetTcpTable';
end.

Вызов GetTcpTable:

{$R-}
    Entries:=16;
    Sz:=SizeOf(TMIB_TCPTABLE)+SizeOf(TMIB_TCPROW)*(Entries-1);
    pMibTable:=nil;
    try
     repeat
       ReallocMem(pMibTable,Sz);
       Res:=GetTcpTable(pMibTable^,Sz,False);
     until Res <> ERROR_INSUFFICIENT_BUFFER;
     if Res <> NO_ERROR then
      begin
       ShowMessage(SysErrorMessage(Res));
       exit;
      end;
     for Entries:=0 to pMibTable.dwNumEntries-1 do
      begin
         <Делать что-то>
      end;
    finally
     FreeMem(pMibTable);
    end;
