I've been using quad9 for a while but want to compare that against Vodafone's DNS servers (FibreX in Wellington). For a long time I've used:
184.108.40.206 and 220.127.116.11
But this page on Vodafone's site seems to suggest the following:
18.104.22.168 and 22.214.171.124
I'm experimenting with pi-hole / dnsmasq filtering so hopefully don't need quad9, cleanbrowsing etc. to do the filtering for me.
