[SOLVED] Isatap, configure preferring ipv4 only for one subnet

Hey guys,

Quick question, on ubuntu 16.04 with isatap installed. How do I configure gai.conf to only prefer ipv4 for one specific net?

My precedence list today.

precedence ::1/128 50
precedence ::/0 40
precedence 2002::/16 30
precedence ::/96 20
precedence ::ffff:0:0/96 10

I would like to add to that list so that net: 2a33:9fc0:b:100e/64 is ipv4 only.

Anyone?

Solved,

Adding like this:

precedence ::1/128 50
precedence ::/0 40
precedence 2002::/16 30
precedence ::/96 20
precedence ::ffff:0:0/96 10
precedence 2a33:9fc0:b:100e/64

Would not work, but adding with the additional "::" did it.

precedence ::1/128 50
precedence ::/0 40
precedence 2002::/16 30
precedence ::/96 20
precedence ::ffff:0:0/96 10
precedence 2a33:9fc0:b:100e::/64
