[dns-operations] OpenDNS and IPv6 - it does not really get it does it

Ever heard that nice "your PoP does not work!" kind of claim.
Well, check this one:
root at openwrt:~# ping 2001:15c0:65ff:268::1
PING 2001:15c0:65ff:268::1 ( 56 data bytes

--- 2001:15c0:65ff:268::1 ping statistics ---
85 packets transmitted, 0 packets received, 100% packet loss

Note it is an OpenWRT, thus a Linux variant. Linux requires ping6
instead of ping and this is also reflected in the IPv4 address between
() and there lies the fun detail: = hit-nxdomain.opendns.com.

Can the OpenDNS guys *PLEASE* not mangle DNS responses?
(and/or at least make sure that when there is a ':' in the name, which
afaik DNS never should have in the first place, that they don't respond
with the above nonsense)

Thank you.


(forwarded to this list, as most likely other people will also get
"operational problems" because of people using the opendns service....)
