best way to reveive both ipv4 and ipv6 connections

[Mihir Luthra]

Hi everyone,

I was working on making rwhod ipv6 clean. I have done some work so far but
then I realised I can't receive ipv4 connections on AF_INET6 sockets.
On googling I found its insecure and freebsd disables it by default. [1]

I needed some advice on what would be the best way to receive connections
then?
Should I use 2 separate sockets with conditions?
