I want to adapt my old C codebases, that were written for IPv4, to work with IPv6. What do I need to change so that my C code works with both IPv4 and IPv6?

Find all code that uses
inet_aton,inet_ntoa,gethostbyname,gethostbyaddr,htonl,htons,ntohl,ntohs, and any directsockaddr_inmanipulation and replace it with simple calls togetaddrinfoorgetnameinfo. This will make your code much simpler and more maintainable and IPv6 will automatically work with no additional effort.
