How to convert string to IP address and vice versa

Question

how can I convert a string ipAddress (struct in_addr) and vice versa? and how do I turn in unsigned long ipAddress? thanks

Answer 1

I'm not sure if I understood the question properly.

Anyway, are you looking for this:

std::string ip ="192.168.1.54";
std::stringstream s(ip);
int a,b,c,d; //to store the 4 ints
char ch; //to temporarily store the '.'
s >> a >> ch >> b >> ch >> c >> ch >> d;
std::cout << a << "  " << b << "  " << c << "  "<< d;

Output:

192  168  1  54
