如何用delphi程序获取IP地址！

procedure GetIPList(IPList: TStringList);
type
TaPInAddr = array [0..10] of PInAddr;
PaPInAddr = ^TaPInAddr;
var
PHE: PHostEnt;
PPtr: PaPInAddr;
Buffer: array [0..63] of char;
I: Integer;
GInitData: TWSADATA;
begin
WSAStartup($101, GInitData);
GetHostName(Buffer, SizeOf(Buffer));
PHE := GetHostByName(Buffer);
if not Assigned(PHE) then Exit;
PPtr := PaPInAddr(PHE^.h_addr_list);
I := 0;
while pptr^[I] <> nil do
begin
IPList.Add(StrPas(inet_ntoa(PPtr^[I]^)));
Inc(I);
end;
WSACleanup;
end;
