CompTIA Network+ IPv6 Addressing

Importance: With the depletion of available IPv4 addresses, IPv6 has become increasingly critical to ensure the continued operation and growth of the Internet. Its extensive address space, simplified address assignment methods, and improved security measures have solidified its importance.
What it is: IPv6, or Internet Protocol version 6, is a network layer protocol that allows data communications over a packet-switched network. It works by assigning an identification and location system for computers on networks and routes traffic across the Internet.
How it works: IPv6 addressing uses a 128-bit hexadecimal method that allows for 340 undecillion possible IP addresses. Unlike IPv4, IPv6 addresses are broken down into eight groups of four hexadecimal numbers, separated by colons, and leading zeros in any group can be omitted.
Exam Tips - Answering Questions on Addressing: Understand the basic structure and format of IPv6 addresses. Recognize that they are written in hexadecimal and separated by colons. Learn the two types of IPv6 addresses: Unicast and Multicast. Comprehend the difference between Stateless and Stateful address configuration. Familiarize yourself with the concept of IPv6 address scopes, especially link-local and global unicast. Practice is key - make sure to practice converting and subnetting IPv6 addresses as well as recognizing different types of IPv6 addresses.
