We're using 887VA's at branch offices and leveraging IOS ip dns server for split DNS with IPv4 clients.
Is there a way to have DNS server listen on IPv6 also?
So far I've been unable to locate any specific documentation on this feature, but there are some previous threads hinting it supported on some platforms.
Current config, the ISR doesn't respond to IPv6 request even after removing the default restrict source.
Any advice or pointers would be appreciated.

This thread reports 1921 works but not the 1841. I'm using the 887VA which is newer than the 1921.
Where can one find which platforms are supported?
