However, if your resolvers are not reliable, they slow down your internet, or you want to use faster and more private servers, Windows 10 allows you to change these settings using Control Panel, Command Prompt, and Settings app. Typically, you won't notice this process because everything happens in milliseconds. When the address is found, it returns, and then the browser connects to the site and downloads the page's contents. Although you can type to get to our website, in the background, the browser first sends a request to the DNS servers to resolve the website name into an IP address. These exact steps vary on your router but some hints can be found here. I would configure a static unique local prefix for your network and assign a static address to your pi and enter it in your router configuration page and in /etc/pihole/nf and run pihole -g. Currently these are pseudo static (they change once your internet connection is disconnected) unless you pay the premium for a true static prefix. The problem with global unicast addresses is that they can be at most as static as the IPv6 prefix assigned by your ISP. The global unicast addresses are derived from them and usually thus share the interface identifier.įor a DNS server reachable over IPv6 you need at least a unicast address in order to solve conflicts once a device is connected to multiple interfaces. Link local addresses are usually auto generated by your network devices. Link local addresses can cause problems with your devices because they are only unique on a single interface and have no information on which interface to talk to. Your home network only uses the first and third ones. There are three categories of IPv6 addresses link local (fe80::/64), unique local (fd00::/8) and global unicast (2000::/3). The changes from step 4 tell unbound to use IPv6 and even prefer it for making upstream DNS queries. Depending on the interface configuration of unbound this might be contra productive. Your third step is redundant since pihole only needs a single ip to talk to unbound. The problem with your setup is that your router advertises itself or any other configured IPv6 address as a DNS server for the IPv6 configuration. As u/jfb-pihole already said, AAAA (IPv6) queries can be made over IPv4.
