Description: IPv6 has much larger address space available compared to IPv4. IPv6 uses 128 bit address space while IPv4 uses just 32 bit address space. This increase in address space allows expansion and flexibility in allocating addresses along with making routing easier and cleaner due to hierarchical addressing. As explained in previous video IPv6 also allows auto-configuration for addressing.

In this video I have explained the intricacies of IPv6 addresses, how to write IPv6 address and how these addresses can be abbreviated. IPv6 addresses are written as eight groups of four hexadecimal digits separated by colon ":" e.g.

The version of IP currently being used on the internet is IPv4 and is around for 20 years. IPv4 is remarkably resilient in spite of its age, but it is beginning to have problems. IPv6 has much larger address space than IPv4. IPv6 uses 128bit address as compared to just 32bit address space used by IPv4. The new address space thus supports 2¹²⁸ addresses. This expansion eliminates NATing, gives flexibility in allocating addresses and routing. The other important features implemented by IPv6 include stateless auto-configuration, network renumbering with router announcements, standard subnet size, mandatory security at network layer etc. As of now IPv6 is implemented on all major operating systems in use in commercial, business, and home consumer environments.

IPv6-101 video series on SecurityTube.net will start with the basic introduction to IPv6 protocol. This video series will serve as a IPv6 tutorial for beginners and will help as a quick reference for advanced users. I will try to add more and more practical examples and real life scenarios in IPv6 tutorial video series along with the theoretical explanation.
