Introduction. a dns query is a message that a client sends to the dns server. it contains a list of questions that the dns server answers. a dns query can contain multiple questions that the server will reply to, but a server might also reply with its own additional information. The first answer about using systemd networkd, the third answer is related with openvpn. my answer is not related with anything of that. suppose we have lan with local dns server(172.16.10.100). local domain is ".super" we have client pc in the lan with nic enp0s3. we want to resolve "*.super" via 172.16.10.100 and other requests via 8.8.8.8.

We’re able to set the dns configuration in network interface config files. however, this is not the only way. we can configure a dns service using the etc resolv.conf file. if we want to change our dns configuration, we can use the nameserver keyword: $ cat etc resolv.conf. nameserver 8.8.8.8. nameserver 4.2.2.4. We get the image. following the same rule, we can find the remaining part of the domain — google and com. finally, at the end of the domain, a 00 marks the end of the section. that’s it for the query. with all required information provided by the query, the dns server will send a response message.
