CompTIA Network+: Network Addressing and Routing, IPv4 and IPv6
This guide will discuss the concept of Internet Protocol versions 4 (IPv4) and 6 (IPv6) in network addressing and routing as they are network protocols that determine how data is sent and received over the Internet.
What is it?
IPv4 is an older protocol which uses 32-bit address representation allowing for approximately 4.3 billion unique addresses. IPv6 is a newer protocol developed to overcome the address space limitations of IPv4. It uses 128-bit address representation, vastly increasing the number of possible unique addresses.
How it works?
These protocols work by encapsulating the data into packets, addressing the packets, and facilitating their journey from source to destination.
Why it is important?
IPv4 and IPv6 are pivotal for Internet functionality. As we continue to see an increased number of Internet-connected devices, IPv6's larger address space becomes increasingly necessary. Understanding how these protocols function is critical in network management, and troubleshooting.
Exam Tips: Answering Questions on IPv4 and IPv6
1. Be familiar with the format and structure of both IPv4 and IPv6 addresses.
2. Understand the differences between the two protocols. IPv4 and IPv6 not only differ in terms of address space but also include variations in features and functionalities.
3. Practical knowledge is beneficial. Understand how to configure IPv4 and IPv6 settings in a network.
4. Knowing how to convert IPv4 to IPv6 and vice-versa could be useful.
5. Understand the concept of subnetting in IPv4 and prefix allocation in IPv6.

IPv4 and IPv6 practice test
IPv4 (Internet Protocol version 4) is the most widely used version of the Internet Protocol, which is responsible for addressing devices on a network and facilitating data transmission. IPv4 uses a 32-bit address space, which offers approximately 4.3 billion unique IP addresses. However, due to the growing number of devices connected to the internet, the IPv4 address space has become insufficient. IPv6 (Internet Protocol version 6) was introduced to address this shortage. It uses a 128-bit address space, significantly increasing the number of available IP addresses. IPv6 also introduces other benefits, such as improved security and more efficient routing by removing the need for NAT, better QoS support, and simplified address configuration with Stateless Address Autoconfiguration (SLAAC). Network+ certification examines both IPv4 and IPv6 protocols.
