DNS ATTACK

The Domain Name System (DNS) is the phonebook of the Internet. Humans access information online through domain names, like nytimes.com or espn.com. Web browsers interact through Internet Protocol (IP) addresses. DNS translates domain names to IP addresses so browsers can load internet resources.

Each device connected to the internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.1.1 (in IPv4), or more complex newer alphanumeric IP addresses such as 2400:cb00:2048:1::c629:d7a2 (in IPv6).

A DNS attack is a cyberattack in which the attacker exploits vulnerabilities in the Domain Name System. This is a grave issue in cybersecurity because the DNS system is a crucial part of the internet infrastructure and at the same time, it has many security holes.

There are many different ways in which DNS can be attacked. DNS reflection attacks, DoS, DDoS, and DNS poisoning are just some of the attack types DNS is susceptible to.
