Sensei Says:
"IPv6 doesn't use broadcasts; it relies heavily on multicast. Look out for the link-local address (starts with FE80::/10), which is automatically configured and required for basic IPv6 operations like routing protocol adjacency."

🔑 What are the Key Concepts of Internet Protocol version 6 (IPv6) Address?
- ▸ 128-bit address space represented in hexadecimal.
- ▸ Types of addresses: Unicast, Multicast, Anycast (no Broadcast).
- ▸ SLAAC (Stateless Address Autoconfiguration) and Link-Local addresses.
🎯 How does Internet Protocol version 6 (IPv6) Address appear on the 200-301 Exam?
Compress an IPv6 address according to the rules of zero compression.
Identify the address type (e.g., Global Unicast, Link-Local) based on its prefix.
❓ Frequently Asked Questions
Why did we need IPv6?
Because the rapid growth of the internet led to the exhaustion of available IPv4 addresses.
Can IPv4 and IPv6 run on the same network?
Yes, through a technique called dual-stack, where devices run both protocols simultaneously.
