I am trying to configure IPv6 on a VPS running Debian 10 and executing

ip addr add 2a02:x:x:x::1/64 dev eth0

works and ip -6 addr show produces the following output:

inet6 2a02:x:x:x::1/64 scope global
   valid_lft forever preferred_lft forever
inet6 fe80::x:x:x:2358/64 scope link
   valid_lft forever preferred_lft forever

The next step was to configure IPv6 in /etc/network/interfaces where I have the following section:

iface eth0 inet6 static
    address 2a02:x:x:x::1
    netmask 64
    gateway fe80::1
    accept_ra 0
    autoconf 0
    privext 0
    dns-nameservers 2a02:c207::1:53 2a02:c207::2:53

However, after a reboot, ip -6 addr show produces only this output:

inet6 fe80::x:x:x:2358/64 scope link
   valid_lft forever preferred_lft forever

What am I missing?

IPv4 configuration works fine where I assign two IPv4 addresses to eth0.
