If the bind has been started, we can use the/etc/init. d/named reload command to reload the configuration file. As follows:
Since this machine has already set up a DHCP server, we can modify the DNS address obtained by the client through The DHCP Service as follows:

This article describes how to check whether the local DNS server works normally and how to update it. When we access a website, we directly enter the domain name in the browser, for example, www.webweb.com, when a website fails to be accessed normally, many users instinctively think that there is a problem with the local network or the target server.

Each IP address can have a host name that consists of one or more strings separated by a decimal point. With the hostname, do not memorize each IP device IP address, just remember the relative intuitive meaningful host name on the line. This is the function that the DNS protocol will perform.Today we will discuss DNS servers, especially Linux DNS servers, and how
