ping & "invalid value for argument address"

I've experimenting with IPv6 and I am getting following error with a ping command:
Code: Select all
[admin@Ranume] > ping ipv6.google.com
invalid value for argument address
[admin@Ranume] >
What does it mean?
Is the MT (MikroTik RouterOS 5.0beta2) ping command supposed to work with IPv6 or not?

[PPPoE7] > ping ipv7.google.com
invalid value for argument address
Its normal, mikrotik just cant find IP address for DNS name

Why it can not find it?
My other Linux systems using same DNS servers find it just fine.

Don't know if this has anything to do with it, but:
Code: Select all
[tim@wifi03 ~]$ nslookup
> ipv6.google.com
Server:         68.1.18.229
Address:        68.1.18.229#53

Non-authoritative answer:
ipv6.google.com canonical name = ipv6.l.google.com.
> ipv6.l.google.com
Server:         68.1.18.229
Address:        68.1.18.229#53

Non-authoritative answer:
*** Can't find ipv6.l.google.com: No answer
This is a Linux box, not MikroTik.

only thing i can think of is check with other DNS server to resolve DNS.

DNS cahcer in RouterOS is capable to resolve IPv6 addresses correctly (AAAA entries)

Are you sure? It should express itself (more) clearly if it does not get a proper IPv6 address and not just talk about "invalid value...".
For instance on my linux box I get:
Code: Select all
[root@haskaa ~]# dig @194.204.0.1 ipv6.google.com AAAA

But my MT box (MikroTik RouterOS 5.0beta2) has errors with the same DNS servers:
Code: Select all
[admin@Ranume] /ip dns> export
# jun/04/2010 20:44:09 by RouterOS 5.0beta2
# software id = LB5I-W12K
#

    max-udp-packet-size=512 servers=194.204.0.1,194.204.22.2
[admin@Ranume] /ip dns> /ping ipv6.google.com
invalid value for argument address
[admin@Ranume] /ip dns>
What is really wrong with it?

With 5.0beta3 the ping message has changed, but end result is still the same:
Code: Select all
[admin@Ranume] > ping ipv6.google.com  
while resolving ip-address: could not get answer from dns server
[admin@Ranume] > ping 2a00:1450:8007::68

Only thing to conclude is either RB IPv6 DNS implementation is buggy or PING itself will ignore IPv6 name resolving.
Are there any plans to address that issue?
