I have a humble question on whether it's possible for IOS DNS server to sniff and store mDNS (or other way) speaking hosts in order to track SLAAC-ed endpoint IPv6 addresses and their hostnames for comfortable connectivity using FQDNs among IPv6 hosts on different L3 subnets? Based on what I've reserched on CCO the chance is almost none..
I'm preparing CPE design for IPv6 rollout and this would be fine feature to offer with small sized deployments without having to run some central DNS server taking care of this (will be considered, optionally).
I'm sorry but we need to keep Cisco CPE line at this moment :-)
Well, I spent these 3 days in tough condition trying to make IOS DNS server what it's not :-)) A DDNS-capable one. I simply can't understand why such "easy" and rather useful thing compared to milions in IOS code is not supported. From my experiments in IPv4 yet, I can't get DNS server to respond to SOA query as would be needed per RFC 2136 and highlighted by this WinXP doc, which I have referred to :
So, I leave this for whoever might find this issue in coming weeks or months - to help save his time. With very little hope, that someone from related BU could think of it and put it on roadmap. Perhaps.. one day

The need was to reach an host inside a LAN through a VPN connection managed by the LAN gateway (Cisco 1921).
The LAN gateway performs NAT and there was a dedicate nat rule for the host i wanted to reach through VPN.
