Internet Protocols and DNS Overview

What is the purpose of IP addresses on the internet?

Which protocol offers more unique addresses: IPv4 or IPv6?

What role does the Domain Name System (DNS) serve in internet connectivity?

Why are DNS servers distributed hierarchically in zones like.org,.com,.net?

In what decade were the internet protocols invented by Vint Cerf and Bob Kahn?

Which statement best describes the growth of the internet?

What is the primary function of the internet's design philosophy and architecture expressed through protocols?

The internet is a network of networks connecting billions of devices globally through various interconnected networks and protocols invented by Vint Cerf and Bob Kahn in the 1970s.
The internet operates on a design philosophy and architecture expressed through protocols, allowing for seamless communication across different technologies.
Each device on the internet has a unique IP address, similar to a street address, which is crucial for devices to communicate with each other.
IP addresses are hierarchical and organized in bits, with the traditional IPv4 providing over 4 billion unique addresses, while the newer IPv6 offers more than 340 undecillion unique addresses.
Most users interact with domain names rather than IP addresses, relying on the Domain Name System (DNS) to associate names with corresponding IP addresses for internet connectivity.
DNS servers are distributed hierarchically in zones like .org, .com, .net to handle the vast number of requests from devices, but this openness makes DNS vulnerable to cyberattacks like DNS spoofing.
Despite the internet's massive growth, the DNS and IP protocols are designed to scale efficiently to accommodate the increasing number of devices and websites.
