The manufacturer of my WLAN router released a new firmware. It contains IPv6 and DNSSEC support. I got a little bit of time and power to install it. Unfortunately my ISP does not provide IPv6 connectivity.
When I do an IPv6 ping from the laptop to the router, it works, but the IPv6 address does not show up in the Homenetwork overview of the router. Seems they still have some work to do.
Regarding DNSSEC I do not see any options in the management interface, but I assume it just means that the DNS server does the right thing when he is confronted with recursive DNSSEC requests. No idea if he will validate himself and if yes, if he will add some log messages regarding it or not.
