gethostbyname replacement for IPv6 addresses

Question

Hi,

I have a program that uses gethostbyname (in Windows) in order to convert IP address to hostname.

But, it works only for IPv4...

What is the correct replacement for IPv6?

Thanks.

Answer 1

Looking up gethostbyname in MSDN tells us that it's deprecated and we should look at getaddrinfo, which has all kinds of options for dealing with other addressing families.

Or if you're doing address to name translation, you'll end up at getnameinfo

Answer 2

Use getaddrinfo, which deprecates the old gethostbyname function.
