Ehhh. For something as forward looking as anima , it is unfortunate that
you believe you will need to bring this technical debt with you.

My suggeation is that you require ipv6 for this case. If you do not shed
this requirement now, you will carry it with you forever.

The iphone can require ipv6 apps, so can anima.
