Hello, in case when machine has both A and AAAA records, there is an address selection policy algorithm which determines which address to use first. https://www.freebsd.org/cgi/man.cgi?query=ip6addrctl&sektion=8
I use it in "prefer ipv4" form, to use ipv4 first when available. All programs like ssh work as expected. In haproxy backends are resolved always to ipv6, even when there is an ipv4 address. Is it possible to make it to respect address selection policy? Thanks.
