Fair enough, that is why IPV6_V6ONLY is used in my example. The bad thing is that the return value is independent of whether I impose net.ipv6.bind6only=0 or not. A clearly viable conclusion is that eglibc prefers to return an IPv4 wildcard, whereas glibc preferred to return the IPv6 wildcard first. > By the way the getaddrinfo code is identical in glibc and eglibc, > so please stop blaming eglibc. > The differences in return order for the address families must therefore be sought in some other mechanism.
