My original response was to write essentially the same C program you did 
except converting the 4 octets into a single int:
int ipaddr;
	ipaddr = ntohl(a << 24 | b << 16 | c << 8 | d);
	printf("%x\n", ipaddr); 


> main(int ac, char **av)
> {
>     int a,b,c,d;
> 
>     sscanf(av[1], "%d.%d.%d.%d", &a, &b, &c, &d);
> 
>     printf("%02x.%02x.%02x.%02x\n", a, b, c, d);
> }
