+ # todo: can our ptr records be put in /etc/hosts?
+ # eg: user normal /etc/hosts records, and they wont be used for A resolution
+ # due to the other settings, but will be used for ptr? then maybe
+ # we dont have to restart dnsmasq for a dns update?
+ #
+ # todo: according to this
+ # https://www.redpill-linpro.com/techblog/2019/08/27/evaluating-local-dnssec-validators.html#toggling-dnssec-validation-1
+ # we should turn on dnssec validation when wrt gets version > 2.80. currently at 2.80.
+ # todo: download https://downloads.openwrt.org/snapshots/packages/mipsel_24kc/base/dnsmasq-full_2.84-1_mipsel_24kc.ipk
+ # and install it. then we can turn off dnssec in systemd-resolved
+ #
+ # Also, reload of dnsmasq seems to break things, wifi
+ # clients were not getting internet connectivity.
