已知网址,如何将其变换为IP地址

肯定有API函数，查查吧，
比如同ping一样的命令

[]UP

uses
WinSock;

function GetIPByName(AName: string): string;
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);
Result := '';
StrPCopy(Buffer, AName);
phe := GetHostByName(buffer);
if phe = nil then
Exit;
pptr := PaPInAddr(Phe^.h_addr_list);
I := 0;
while pptr^ <> nil do
begin
Result := StrPas(inet_ntoa(pptr^^));
Inc(I);
end;
WSACleanup;
end;

procedure TForm1.Button1Click(Sender: TObject);
begin
ShowMessage(GetIPByName('www.google.com'));
ShowMessage(GetIPByName('www.Delphibbs.com'));
ShowMessage(GetIPByName('www.163.com'));
end;

接受答案了.
