It's normal, no? They deploy IPv6 because they don't have enough IPv4 addresses. And since most servers in the world are not IPv6 ready and will never be for a long time, if you want to reach an IPv4 server you have to go through their CGNAT which may have a piss-poor performance.
I really wish RIPE could force ISPs to release the addresses they don't need :(
