getaddrinfo function in posix/host_resolver returns only IPv6 resolved addresses in my target platform(ARM uclibc).The same function returns both IPv4 and IPv6 addresses in my host environment(Ubuntu glibc).

After I changed hints.ai_family to AF_INET, I do get IPv4 addresses. A quick google search revealed similar problems related to hosts files settings. I tried them but nothing helped.

I would like to keep the AWS core libraries unmodified. is there any other solution to fix IPv4 issue.

Can you provide a minimum code sample where while using the sdk that reproduces this?

Also, is ipv6 a valid route? The getaddrinfo usage is designed to return usable addresses. Usually if an address family isn’t being returned, it’s because it’s not a valid route.
