AP CSP: The Internet

Internet Protocol

• Protocol that breaks data down into packets and addresses them with source and destination information

• A DNS attack in which numerous pings are made to the same IP, causing it to crash

• Protocol used by the World Wide Web. It describes how messages are formatted and interchanged, and how web servers respond to commands.

• Protocol that provides reliable, ordered, and error-checked delivery of a stream of packets on the internet

Tranmission Control Protocol:

• Breaks messages into packets and addresses them
• A DNS attack in which numerous pings are made to the same IP, causing it to crash
• Protocol used by the World Wide Web. It describes how messages are formatted and interchanged, and how web servers respond to commands.
• Provides reliable, ordered, and error-checked delivery of a stream of packets on the internet

The world is currently in a transition to using IPv6, a newer version of the IP protocol that uses 128-bit addresses instead of 32-bit addresses used by IPv4. What is the main problem that IPv6 was created to solve?

• IPv6 will allow problems with IPv4's address hierarchy to be resolved
• 32-bit addresses could not ensure that every internet-connected device can receive a unique IP address
• 32-bit addresses could not accommodate the increased size and amount of data traveling on the Internet as it has grown in popularity
• IPv4 proved unreliable in some cases where network redundancy could not be ensured
