    Adding your FRiTZ!Box as a “secure” DNS resolver for the fritz.box pseudo-domain

    Your FRiTZ!Box maintains a useful list of names of machines in your local network in its pseudo-domain fritz.box, based on DHCP requests and web interface. This information is useful, but adding the pseudo-domain “fritz.box” to your own DNS hierarchy is no longer straightforward in the days of DNSSEC. Here is how to include it into…
