Are you sure it is DS-Lite? My understanding is that DS-Lite is only used on "fixed" networks and that mobile networks use IPv6 only with IPv4 via DNS64/NAT64.

Kyivstar deploys both mobile and fixed networks do they?

Which would be the usual way for IPv6 on;y mobile networks.

 AS>  Using other DNS servers works, though.

Maybe they still need to iron out the theething problems.
