No, it's not working for me.
Only IPv6 works when I set it to 0. But at the same time, IPv4 doesn't work.

I've also heard that setting sin6_addr to in6addr_any will work for both
IPv4 and IPv6, that's why only I was looking for in6addr_any in the stack.

So, my ultimate question is whether in6addr_any is equivalent to setting
sin6_addr=0 or there is something unique with in6addr_any variable which
allows both IPv4,v6 to work?
