our costumer is trying to use 2 content filters at the same time , one by us and another by our competitor . Does both can work at the same time ? what happens if one has rule of block traffic on port 4477 and other has allow traffic on port 4477 ?

This is happening Mac M1 Monterey OS .Environment supports both IPv4 and IPV6. When a http client calls gettaddrinfo() it is returning both IPv6,IPv4 IPs . first v6 IPs and then v4 IPs. We need to have a way to sort gettaddrinfo() output to get v4 ip first and then v6. We tried changing DNS order with scutil by putting v4 DNS first , but still getaddrInfo() listing v6 IPs first . In linux there is a way to control gettaddrinfo() o/p with /etc/gai.conf https://man7.org/linux/man-pages/man5/gai.conf.5.html . In Mac I did not find any option like this , scutil changing order DNS is not effective . can you tell us what is way to do this in MAC OSx ?
