Thankfully with nearly everything running over https these days that's not the issue it used to be | |

But I think it is generally assumed that of someone talks about "changing their DNS server away from the ISP" that they want to change it to something which can actually answer the queries, i.e. they pick one of the several public recursive resolvers which are explicitly marketed as an alternative to the ISP's DNS server. | |
| Oct 11, 2020 at 19:47 | comment | added | Gnudiff | It might perhaps be useful to note that a lot of DNS servers only serve their zones. For example, my company's DNS server will only answer requests about my company's IP addresses/names and will drop all other queries. This was, of course, more important in earlier days before Google's DNS servers. As far as I remember we couldn't just use any semi-public DNS servers, but only those who were prepared to accept queries from any country. | |

However you will have to maintain the IP address manually, and it is also a very imperfect protection against leaking hostnames. Not even specialized Tor Browsers are flawless in this regard. | |
