IPv6 routing independent of host

Hello,

Are there any plans or service to offer an IPv6 routing, independently for the host IPv6 range ?
For IPv4, failover IP works fine, but they do not support IPv6...
So if you setup an IPv6, it will be within the range of an host, and if you ever have to move a container or VM to another host, then the IPv6 will have to be changed, and DNS will need to be updated, which is error-prone and introduces extra delays.
