Common failures in computer networks: DNS errors

What is a DNS ?, in computer responds to the acronym Domain Name System.

Thanks to the DNS servers we know the names in the networks, such as those of the Internet or those of a private network. That is, we know the IP address of the machine where the domain we are going to access is hosted.

Basically DNS servers help us to solve names, to access for example google.com, after writing it in our browser, the system first searches for it, finds it and then we see the page in our browser. It may be the case that our operating system tells us what we have access to the Internet, but when trying to access any Web, we do not see the same or give us an error, as an example it can be NAME NOT RESOLVED, for this we must verify the DNS or The domain name
