Ever wanted to get your computer’s local ip address?  Well here’s a code snippet to help you along!

{——————————————————————————}

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^[I] <> nil do
begin
Result := inet_ntoa(pptr^[I]^);
Inc(I);
end;
