Domain Name Server (DNS) Fundamentals: Exploring Traceroute, DNS Attacks and Beyond

By Telang and Tarun Telang

DNS translates human-readable domain names into machine-readable IP addresses. Despite its importance, DNS is one of the most misunderstood components of network infrastructure.

When DNS is not working properly, you can't get access to websites. When it is not configured correctly, it can lead to slow loading times and connectivity issues. If compromised by hackers, it opens the door to serious security breaches and cyberattacks.

"DNS Fundamentals: Exploring Traceroute, DNS Attacks, and Beyond" is your go-to guide for understanding this essential internet protocol.
