Additional IPv6 of OVH US VPS

ask_seek_knock

Hello everyone,

I have a OVH US VPS with an IPv4 and an IPv6 (/56). Now I failed to add additional IPv6s.

The network manager is systemd-networkd, and I've tried to append addresses in /etc/systemd/network/20-wired.network then sudo systemctl restart systemd-networkd

Additional IPv6s can be set in control panel when using other providers, but I saw no related functions in "https://us.ovhcloud.com/manager/#/dedicated/ip?serviceName=vps-blah-blah.vps.ovh.us"

So is it possible to add additional IPv6s to OVH US VPS, and how if possible.

Thank you.

Maybe this link will shed some light on your problem: https://www.linode.com/docs/products/compute/compute-instances/guides/systemd-networkd/#configuring-additional-ip-addresses

Or you can add them manually with ip addr add IPv6PREFIX::cafe:1 dev eth0 Note that they will be gone on reboot.

Thanks for replying, but maybe you misunderstood my meaning:
What your link points to is what I've tried.
Adding IPv6 to VPS is OK, and here is the result:

user@ovh02:~$  ip -6 a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 state UNKNOWN qlen 1000
    inet6 ::1/128 scope host noprefixroute 
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 state UP qlen 1000
    inet6 2604:2000:123:123::abcd:cdef/56 scope global 
       valid_lft forever preferred_lft forever
    inet6 2604:2000:123:123::1234/56 scope global 
       valid_lft forever preferred_lft forever
    inet6 fe80::cdef:abcd:0123:1234/64 scope link proto kernel_ll 
       valid_lft forever preferred_lft forever

One of the IPv6 above is the default IP, which is OK, and the other one is what I've added, which is not working.

Here is the content of /etc/systemd/network/20-wired.network:
user@ovh02:~$ cat /etc/systemd/network/20-wired.network
[Match]
Name=eth0

[Address]
Address=12.34.56.78/24
[Route]
Gateway=12.34.56.1

[Address]
Address=2604:2000:123:123::1234/56
[Route]
Gateway=2604:2000:123:123::1

[Address]
Address=2604:2000:123:123::abcd:cdef/56
[Route]
Gateway=2604:2000:123:123::1

As you can see, the setting of 2 IPv6s are identical, so I think the root of error is not my local configuration, but somewhere of OVH control panel or something.

Maybe I should open a ticket, but previous experience with support is not good:
the support staff behaved like a robot, which couldn't know what I mean, only recommend "upgrade the service" or "we are investigating and be patient".

Thank you anyway.

Solved. It's prohibited. (Hope admin of let to append a [Solved] mark to the title, would you?)
