- IPv6 provides global multicast support. If you can route to it you can multicast to it!
- IPSec provides
Certificate based authentication
- 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
- TTL is now a hop count rather than time based for simpler calculation
- Routers do not fragment IPv6 Packets
Maximum packet size must be established prior to transmission
- 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
Mobility → IPv6 has the ability for entire subnets to move from one router to another router without needing address re-assignment
MTU → TTL is now a hop count rather than time based for simpler calculation
Compressing 0's → 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
Anycast → 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
More Addresses → Global address
