ping ipv6 addresses

Hello!

I create 6-to-4 tunnel and ping ipv6.google.com, but i see:

 ping ipv6.google.com
invalid value for argument address:
    invalid value of mac-address, mac address required
    invalid value for argument ipv6-address
    failure: dns name exists, but no appropriate record

If enter ping [:resolv ipv6.google.com]:

 ping [:resolv ipv6.google.com]
  SEQ HOST                                     SIZE TTL TIME  STATUS
    0 2a00:1450:4008:800::1005                   56  55 122ms echo reply
    1 2a00:1450:4008:800::1005                   56  55 120ms echo reply
    sent=2 received=2 packet-loss=0% min-rtt=120ms avg-rtt=121ms
   max-rtt=122ms

Why ping not resolv DNS for ipv6 name?

Mikrotik really needs to do some more advancement in the IPv6 feature set IMO, this being a simple example.
