DNS

Intro
DNS (domain name system) controls your domain name's website and email settings. Visitors go to your domain name and then the DNS settings control which company's server it reaches out to.

Usages:
It is mainly used as a control for the company/organisations website or email settings.

Advantages:
·     To redirect clients is that it is a natural way of informing the clients about the service addresses. It is used by many existing network services, and is very likely to be used by those to come as well.

·    It is supported by millions of DNS servers

Disadvantages:
·     DNS queries carry no information about the client that triggered the name resolution.
