27.11.2021 · The default ULA (Unique local address) prefix represents an address that is not globally routed on the internet by design. A lot of clients will prefer IPv4 over a ULA IPv6 address if there is no global IPv6 address assigned, so you may need to change your existing ULA prefix to indicate a global address to ensure traffic goes over IPv6 by default when possible.

Nov 26, 2018 · * OpenWrt 18.06.1 r7258-5eb055306f / LuCI openwrt-18.06 branch (git-18.228.31946-f64b152) - Steps to reproduce 1.

FYI: the ULA-Prefix here is the common network portion of the address (first 4 quartets), and the IPv6-Suffix (last 4 quartets) is the unique self-generated host portion. To provide the Pihole as DNS for all local IPv4 devices , go to Interfaces >> LAN >> DHCP Server >> Advanced Settings and set DHCP-Options using: 6,x.x.x.x,y.y.y.y (x.x.x.x and y.y.y.y are the static IPv4 addresses for your ...
