- When IPV4 was created, it supported over four billion…devices that could connect to the internet.…However, as more and more devices were created,…the number of available addresses started to run out.…So another way needed to be created.…Luckily, the internet protocol's designed to scale…and expand to meet new demands.…So in 1995, a new version of the internet protocol…was created, it's called IPV6.…Now you might ask yourself, what happened to IPV5?…Well, part of how specifications are developed is…that new ones could be created and designed,…but when they get to a certain point they're given a name.…
In 1979, an experimental protocol called the internet…stream protocol was assigned the number five,…but it was never finalized.…In 1995, the Internet Engineering Task Force, or IETF,…needed to create a new way to provide addresses…on the internet, now to expand beyond the…four billion limit of IPV4.…The result was to increase the number of bits used…to store an address.…IPV4 uses 32 bits.…
IPV6 uses 128.…With 128 bits, we can store a bunch of addresses.…
This course is the second in our Computer Science Principles series, designed around the AP Computer Science Principles (CSP) curriculum. It is a great foundation for anyone, at any age, to prepare for careers in technology and computer science. Understanding basics like the Internet will help you understand the interplay between hardware, software, data, networks, and the people that use them.
- How the Internet was born
- Sending and receiving information on a computer
- IP addressing
- DNS, routers, and packets
- Identifying web servers with URLs
- HTTP and HTML
- Encrypting data that's sent over the Internet
