How to add a range of ipv6 addresses on Ubuntu 14.04?

Question

linux

There is some subnet that the hosting assigned to my server of the form AAAA:AAAA:AAAA:AAAA::
The task is to connect all the ips of this subnet to the server for use in applications on it (so that you can use everything, manually adding several is not an option ).
Current configuration /etc/network/interfaces:

auto lo
iface lo inet loopback

auto eth0
iface eth0 inet dhcp
iface eth0 inet6 auto
