for my home network, i use adguard in combination with my opnsense for dns.upstreams, if it needs to leave my network, are the usual suspects: google, cloudflare, and quad9 - selected based on performance

for my servers/domains i used to just be a regular BIND user, editing the zonefiles manually when needed.... but i have since switched my dns over to cloudflare because "easy and no maintenance"

(i might be one of the weird ducks in this sub: i still do my mailserver myself, but outsourced my dns to cloudflare...)

though, to be honest, there are quite a few additional reasons i did the cloudflare move:

• the use of their cdn
• hiding the actual server IPs
• using their zero trust

pro tip: if you do not read the ToS, you also can't lie about if you are breaking them or not

came here to say basically the same thing: preservation
