Public and Private IPv6 Addresses | Free CCNA Training Course
Welcome to the Free CCNA Training Course. This series is for anyone who wants to build on their basic network skills, and even pass the CCNA 200-301 exam.
Section 3 of this series covers IPv6. This covers topics such as an IPv6 overview, how IPv6 addresses work, address types, address assignment, and routing with IPv6.
The website has additional links for further study to take you to the next level. Links are at the end of the description.
In this video, we’re going to cover:
0:00 Public Address Space
2:33 Local Addresses
4:38 Multicast and Anycast
6:16 Subnetting
IPv4 addresses were all meant to be public. Unfortunately, running low on address space means we needed to use private IPs and NAT. IPv6 is going back to this model by making most addresses ‘Global Unicast’ addresses. Most addresses will be routable on the internet.
Each IPv6 enabled interface has a link-local address, starting with fe80. This is used for all communication over the local link. This includes NDP communication. Link-local addresses are usually assigned automatically using EUI-64.
Unique local addresses are similar to private addresses in IPv4. They are routable on your local network, but not over the internet. They generally aren’t recommended.
There are no more broadcasts in IPv6. This is now handled by multicast, which is far more efficient. A new type of traffic is Anycast, where multiple devices can have the same IP. Any one of them can respond to a client’s request.
IPv6 and IPv4 can work side-by-side. This is called dual-stack, and is one of the methods of migration to IPv6.
IPv6 is routable like IPv4, and can be subnetted in the same way. /64 networks are the most commonly used.
