- IPSec provides
Certificate based authentication
- IPv6 provides global multicast support. If you can route to it you can multicast to it!
- 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
- When a packet is sent to a multicast address the packet is delivered to all hosts that are assigned that multicast 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
- TTL is now a hop count rather than time based for simpler calculation
5 True/False questions
Link-Local → 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
Unicast address types → Global address
Mobility → IPv6 has the ability for entire subnets to move from one router to another router without needing address re-assignment
Unicast → Unicast addresses identify a single network interface. This is the most common type of address used. And is analogous to an IPv4 address
Need for IPV6 → Address Exhaustion
