[Ipv4 as default]

Hello, 

 

My router has default as ipv6. But I need ipv4 as default. 

 

I tried to find email or relevant contact form (that's not from the 90s). But turns out it doesn't exist. 

 

I wrote an email to myservice@magenta.at, no reply. Not sure if proper customer service exists in Magenta. 

 

How do I get magenta to do this simple task? Thanks!
