- Unique local address are similar in nature to IPv4 private Addresses in that they are not assigned by a numbering authority, however they are probably globally unique and are routable within participating sites
- Long strings of zeros may be shortened with :: (you can only substitute once in an address!)
2001:DB8:0:0:8:800:200C:417A becomes 2001:DB8::8:800:200C:417A
- Link local address are addresses that are automatically configured using the interfaces hardware address.
These addresses are not routable!
Link local address use the prefix fe80::/10
- Routers do not fragment IPv6 Packets
Maximum packet size must be established prior to transmission
- An Anycast address is an address that is applied to more than one interface.
When a packet is routed to an Anycast address it is delivered to the first interface discovered configured with that Anycast address
- IPv6 uses a fixed length subnet mask. All Subnets are /64
Simplified packet header.
This facilitates efficient routing
No header checksum to calculate
-Link layer and higher layer checksums are relied upon for header integrity
5 True/False questions
Security Support Mandatory → IPSec provides
Certificate based authentication
More Addresses → Global address
Benefits of IPV6 → Address Exhaustion
Unicast address types → IPv6 uses a 128 bit address space
That is about 340,282,366,920,938,000,000,000,000,000,000,000,000 addresses
Multicast → Unicast addresses identify a single network interface. This is the most common type of address used. And is analogous to an IPv4 address
