How to use ipv6 with Vagrant and VirtualBox?

Question

I have a Vagrant setup running Ubuntu in VirtualBox. I'm trying to create a public virtual network interface that I can access from the host. I have had no problem doing this with ipv4. Using ipv6 I set the interface up like:

guest$ ip link add derpcraft link eth1 type macvlan mode bridge;    
guest$ ip -6 addr add fdfe:dcba:9876:ffff::/64 dev derpcraft
guest$ ip link set derpcraft up

The interface looks like:

        derpcraft Link encap:Ethernet  HWaddr 26:22:d5:54:95:00  
                  inet6 addr: fe80::2422:d5ff:fe54:9500/64 Scope:Link
                  inet6 addr: fdfe:dcba:9876:ffff::/64 Scope:Global
                  UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
                  RX packets:264 errors:0 dropped:0 overruns:0 frame:0
                  TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
                  collisions:0 txqueuelen:0 
                  RX bytes:52989 (52.9 KB)  TX bytes:2040 (2.0 KB)

From the host machine I can't seem to ping this either address on the interface.

host$ ping6 fe80::2422:d5ff:fe54:9500
ping6: UDP connect: No route to host
host$ ping6 fe80::2422:d5ff:fe54:9500%::1
ping6: UDP connect: No route to host
host$ ping6 fdfe:dcba:9876:ffff::
ping6: UDP connect: No route to host
host$ ping6 fdfe:dcba:9876:ffff::%::1
ping6: UDP connect: No route to host

I think I may need to configure Vagrant or VirtualBox to accept ipv6 connections.

Another point. My current ISP is not ipv6 friendly yet. I don't suspect that has anything to do with it because this should all be a local request.

Update: For good measure I gave the interface an ipv4 address like:

guest$ ip address add 192.168.33.11/24 broadcast 192.168.33.255 dev derpcraft
guest$ ifconfig
derpcraft Link encap:Ethernet  HWaddr 26:22:d5:54:95:00  
          inet addr:192.168.33.11  Bcast:192.168.33.255  Mask:255.255.255.0
          inet6 addr: fe80::2422:d5ff:fe54:9500/64 Scope:Link
          inet6 addr: fdfe:dcba:9876:ffff::/64 Scope:Global
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:1736 errors:0 dropped:0 overruns:0 frame:0
          TX packets:24 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:418224 (418.2 KB)  TX bytes:2040 (2.0 KB)

And I can ping that form the host no problem:

host$ ping 192.168.33.11
PING 192.168.33.11 (192.168.33.11): 56 data bytes

round-trip min/avg/max/stddev = 0.388/0.437/0.497/0.045 ms

Update: The host interface looks like:

host$ ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 16384
    options=3<RXCSUM,TXCSUM>
    inet6 fe80::1%lo0 prefixlen 64 scopeid 0x1 
    inet 127.0.0.1 netmask 0xff000000 
    inet6 ::1 prefixlen 128 
gif0: flags=8010<POINTOPOINT,MULTICAST> mtu 1280
stf0: flags=0<> mtu 1280
en0: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 04:0c:ce:e4:1f:be 
    inet6 fe80::60c:ceff:fee4:1fbe%en0 prefixlen 64 scopeid 0x4 
    inet 192.168.1.72 netmask 0xffffff00 broadcast 192.168.1.255
    media: autoselect
    status: active
p2p0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 2304
    ether 06:0c:ce:e4:1f:be 
    media: autoselect
    status: inactive
vboxnet0: flags=8842<BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 0a:00:27:00:00:00 
vboxnet1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
    ether 0a:00:27:00:00:01 
    inet 192.168.33.1 netmask 0xffffff00 broadcast 192.168.33.255

Which shows neither of the VirtualBox interfaces have inet6, and this is probably the issue, but i'm not sure how to enable it.

Solution

It looks like using vagrants public_network option will bridge the virtualbox interface to the host interface piggy backing IPV6

Just to be clear, this is VirtualBox on a FreeBSD host?

this is a OSX host
