Reverse DNS broken for 2001:6f8/32 (Easynet)

Hello,
reverse DNS seems to be broken for 2001:6f8/32 address space due to the non-existing (?) nameserver ns2.easynet.net. I don't know for sure whether such a setup is allowed, but it definitely breaks the dig tool:
kristov@peacock ~ $ dig +trace -x 2001:6f8:13da:1::1
; <<>> DiG 9.8.1 <<>> +trace -x 2001:6f8:13da:1::1
