Chapter 10  Converting Binary and Text Addresses

The IPv4 function calls convert IPv4 addresses as follows:

The inet_aton() or inet_addr() functions convert dotted-decimal string (such as 10.9.8.7) to 32-bit binary in network byte order.

inet_ntoa() converts 32-bit network byte order binary into dotted-decimal string (such as 10.9.8.7).

Two new IPv6 functions convert both IPv4 and IPv6 addresses.
