Onderwerp: How to configurate IP adress from visitor

Hello,

I am searching for a way to configurate the server so that it will only fetch IP4 adresses and not IP6 adresses (SERVER_REMOTE_ADDR) . I see website like ''what is my ip" showing both adresses. Also my research learned me that there are websites that are IP4 only. Long story shot, i am searching for a way to implent something like this. As can be done on apache servers (2 major server software - apache and nginx) there is a config file that has setting for each host. Inside of there you only need the command 
Listen 0.0.0.0:80 to limit to ipv4. 

Long story short. Is this posible to do on Vimmex and of so, how do i do this and that is needed?
