Find out what is you IP adress

Problem/Question/Abstract:

If you want to find out what is your actual IP, this is the right thing for you.

Answer:

Start by creating a new application. Add a Button and two Edit Boxes to your project. Remember not to name them. Just leave them the way they are. In the unit add to uses: winsock.
After that double click on the Button you have just created and in the unit paste the following script instead of the begin function:

function GetIPFromHost
(var HostName, IPaddr, WSAErr: string): Boolean;
type
Name = array[0..100] of Char;
PName = ^Name;
var
HEnt: pHostEnt;
HName: PName;
WSAData: TWSAData;
i: Integer;
begin
Result := False;
if WSAStartup($0101, WSAData) <> 0 then begin
WSAErr := 'Winsock is not responding."';
Exit;
end;
IPaddr := '';
New(HName);
if GetHostName(HName^, SizeOf(Name)) = 0 then
begin
HostName := StrPas(HName^);
HEnt := GetHostByName(HName^);
for i := 0 to HEnt^.h_length - 1 do
IPaddr :=
Concat(IPaddr,
IntToStr(Ord(HEnt^.h_addr_list^[i])) + '.');
SetLength(IPaddr, Length(IPaddr) - 1);
Result := True;
end
else begin
case WSAGetLastError of
WSANOTINITIALISED:WSAErr:='WSANotInitialised';
WSAENETDOWN      :WSAErr:='WSAENetDown';
WSAEINPROGRESS   :WSAErr:='WSAEInProgress';
end;
end;
Dispose(HName);
WSACleanup;
end;


var
Host, IP, Err: string;
begin
if GetIPFromHost(Host, IP, Err) then begin
Edit1.Text := Host;
Edit2.Text := IP;
end
else
MessageDlg(Err, mtError, [mbOk], 0);
end;

After pasting all this just delete the other end; that is left at the end of the source. That's it. This source was not originally made by me but was modified by me. Hope you find it useful. Good luck!
