is characterized by an explicit attempt by attackers to prevent legitimate users of
a service from using that service. It usually leads to overload of system server or
core dump of the system.

3.3.8 DNS
Domain name system (DNS) is an Internet service that translates domain names
into IP addresses. Because domain names are alphabetic, they are easier to
remember. The Internet, however, is actually based on IP addresses. Each time
you use a domain name, a DNS service must translate the name into the
corresponding IP address. For example, the domain name www.example.com
might be translated to 198.105.232.4.
