How to get ns2 ipv6 visible with ifconfig command?
Answered
I have a primary ipv4. I have added myself an additional ipv4.
When using ifconfig or "ip a" command, both ipv4 and my primary ipv6 is showing.
Now I want to add another ipv6 which is like my additional ipv4 to be used as ns2.
So I assigned a ipv6 in ipv6 Ranges as xx:xx:xx:xx:xx/128 similar like the main ipv6 looks.
Also in Basic setup under ns1 and ns2 I added both the ipv4's and ipv6's.
However, this additional ipv6 is not visible with ifconfig and I can not ping it either, so it's not reachable.
What am i doing wrong (or am I fogetting) or what do I need to change?

I will add a screenshot. I read something I need to add a gateway here, but maybe this makes things more clear.
This is how I have it now. I used the complete same range, only the main ip has 2 at the end and the secondary ip has 5 at the end.

Hey hey! This one is likely best handled by your host - while adding the IP to cPanel may make it show up in the interface, it may not properly configure the network settings.

Yes that is odd, because it does work with the ipv4.
Unfortunately the host does not provide support. I could maybe manually add it to the interface, but I don't know for sure if cPanel picks it up then and uses it as ns2 ip.Very odd though, never had these issues with DA and Hetzner and ipv6. Just add and it works.
I expected cPanel to also have it show up on the interface like with the ipv4.

This one I'm honestly not sure - since the issue is happening with basic commands like ifconfig I would hope the host would at least offer some level of support for the network.

Oh I hoped that just as with DA I could just add the ip in some cpanel file and it would work.
Only level of support the datacenter gives is pointing to documentation to do it yourself manually.
If you can assure me that cPanel will use it for ns2 if it sees the ip on the interface then I will add it manually on the interface, ask somebody at their forum probably.

As long as the IP is properly routed to your machine there is no reason you couldn't use it for ns2.

Yes I have a /64 netblock routed to my machine.
I've already asked at the Hetzner forum if they can provide the best way to add it.Did I do it correct in cPanel as far as you can see from the screenshot above with the /128 subnet?

As far as I know, that does look correct.

For future reference and anybody encountering this issue on a Hetzner dedicated server, use this example on RH based systems.
Just edit your network interface file, for example /etc/sysconfig/network-scripts/ifcfg-eno1 and then add this line:
IPV6ADDR_SECONDARIES=<ipv6>/<prefix>
without the hooks, so for example
IPV6ADDR_SECONDARIES=2a01:4f8:xxxx:xxxxx:xxxx:5/128
restart your network and it's working.
You can also add more ipv6 there if needed, seperate the with a space.
Solved.

I'm glad you were able to come up with a working solution!!
