[Bug]: IPv6 address not assigned in netmaker backend container #1070

What happened?

When creating a new network in netmaker and assigning an ipv6 prefix, the auto-generated node IP is not assigned to the wireguard interface but somehow the ipv4 address is assigned twice. Once as /24 and once as /32.

It works correctly on regular netcliend instances but somehow in the container it does not. The eth0 above shows an fe80 so I don't think it's an os issue. This is running with the platform kubernetes env flag.

I can manually assign a v6 address to the eth0 interface but not to any wg interfaces

bash-5.1# ip -6 addr add 2001:470:28:5b2::1/64 dev eth0      <-- works fine
bash-5.1# ip -6 addr add 2001:470:28:5b2::1/64 dev nm-ByteMe
