Ubuntu – (Ubuntu 16.04) IPv6 not working

ipv6

I'm still new to linux/ubuntu, so please bear with me.

I'm trying to get IPv6 working. IPv4 (and my internet) works fine, but when I test for IPv6 on ipv6-test.com it says I don't have IPv6:

My windows machine (on same network) works mostly fine however:

I've tried the code:

test -f /proc/net/if_inet6 && echo "Running kernel is IPv6 ready"

Which brings up "Running kernel is IPv6 ready"

Not sure where to go from here (still learning this). Thanks for any help.

It seems you have to set up DHCP to issue v6 requests on dhclient.conf.

Check this out: https://wiki.ubuntu.com/DHCPv6 (ISC DHCP v6 Client section).

There it suggests you can enable it by adding this line to /etc/dhcp/dhclient.conf:

send dhcp6.oro 1, 2, 7, 12, 13, 23, 24, 39;

If you want to dig further on DHCP client settings refer to its man page, accessible either via the man dhclient.conf and this link: http://linux.die.net/man/5/dhclient.conf
