defeat ipv6

I have two blue plus.

Is there a way to set up the ipv6 dns to allow only ONE ipv6 address which I will point to an old raspberry pi?

 

Will this defeat ipv6 sufficiently to use the ipv4 DHCP on firewalla?

 

I am trying to avoid a separate router.  I will go to one if its the only choice.

 

Thank you, Bradshaw

  +1, my router/modem combo allows setting DHCP IPv6 to 1 address and no less (cannot disable IPv6), but it does not let me reserve it and the Firewalla (Blue) does not pick up the address. It ends up getting assigned to a random device and that device bypasses filtering. 
  
  What other ways are there to defeat IPv6? I can configure the IPv6 DNS servers. But if I set them to bogus addresses it falls back to the ISP provided IPv6 DNS, just as if AutoConfig was set.
  
  Is it possible to create an IPv6 interface on the Firewalla to "steal" this address allocation and prevent it from being assigned to another device?
  
  Thanks in advance.

  Very cool solution, make the ip6 dns point to a fictional site.

   

  I think I’ll set one up on my server and point to it.

   

   

  the random assignment of the ipv6 “victim” is sad.
