Why does dns work badly on linux mint?

Question

Domain Name System

There are difficulties with address replication in linux mint. Often when surfing, an error occurs due to the lack of dns and the inability to connect. Tell me, what is the fundamental difference between the operation of DNS in Linux and Windows? Based on experience, and the logic of things, dns is taken on the trail. chain: system cache - provider dns - some more powerful dns on the network. The question is, how does this chain work specifically on mint/ubuntu? what can be adjusted? forcibly driving 4.4.4.4 or 8.8.8.8 into the dns server gives absolutely nothing. On a Windows machine on the same network, there are no problems.

Answer 1

Comment out the line dns=dnsmasqin /etc/NetworkManager/NetworkManager.confand restart the network.
It does not work well due to the fact that this same dnsmasq messes up. I suffered from this myself. Every time after sleep, for some reason unknown to me, he stopped resolving names, tk. look for the cause of laziness - it's easier to turn it off.

Answer 2

Linux has /etc/resolv.conf file. The file is small but important - it contains the DNS addresses that the system will use when looking up an address or name, up to four, one per line. About file format - man resolv.conf.
For any name-by-address lookup operations and vice versa, the system refers only to addresses from resolv.conf (well, to /etc/hosts, if not disabled) - and only their admins know how these servers work. What and how to check - there are host, nslookup, dig commands - DNS operation is usually checked by these commands.
