adsl拨号上网后,用delphi该如何获取ip地址

1、ping 你计算机名字
2、ipconfig
还有：
uses Winsock;

// returns ISP assigned IP
function LocalIP : 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 := '';
GetHostName(Buffer, SizeOf(Buffer));
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;

//获取本机的IP地址
function getip():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;
IP: String;
begin
Screen.Cursor := crHourGlass;
try
WSAStartup($101, GInitData);
IP:='0.0.0.0';
GetHostName(Buffer, SizeOf(Buffer));
phe := GetHostByName(buffer);
if phe = nil then
begin
ShowMessage(IP);
Exit;
end;
pPtr := PaPInAddr(phe^.h_addr_list);
I := 0;
while pPtr^ <> nil do
begin
IP := inet_ntoa(pptr^^);
Inc(I);
end;
WSACleanup;
getip:=ip;
ShowMessage(IP);//如果上网则为上网ip否则是网卡ip
finally
Screen.Cursor := crDefault;
end;
end;

多人接受答案了。
