Chapter 5.6 IPv6

What are IPv6's 4 improvements that did not exist in IPv4?

1. Built in security 2. Built in quality of service 3. Auto configuration features 4. Source intelligent routing

Compare the IPv6 addresses to IPv4 addresses.

1. IPv6 = 128 bits long , IPv4 = 32 bits 2. IPv6 = does not support broadcast & VLSM, IPv4 = supports broadcast & VLSM. 3. IPv6 = 8 division's within the address 4. IPv6 = Has quartet in each division 5. IPv6 = quartet consists of 4 hexadecimal numbers 6. IPv6 = each quartet is separated by a colon, IPv4 = binary bits are separated by a .(dot) 7. IPv6 Hexadecimal notation has a value of 0-9 or letters A-F 8. IPv6 =Leftmost bits called prefix, IPv4 = network address 9. IPv6 = Rightmost bits called Interface ID , IPv4 = host address

What are 2 ways to shortened the IPv6 format?

1. Omit leading zeros (Ex: 08CA can be written as ---> 8CA) 2. Omit blocks of quartets that are all zeros, replacing all the zeros with a double colon (can only omit one block of the address though bc if you do more, it can get confusing)

What is a unicast address that is assigned to more than one interface, typically belonging to different hosts?

Anycast

What 2 parts is the IPv6 address divided into?

Divided right down the middle of the 8 divisions: 1. Prefix ID 2. Interface ID

What configuration enables a host to communicate with IPv4 and IPv6 hosts?

Dual stack

What is an IPv6 address type that is publicly routable and can be used in the internet?

Global-Unicast

What is the rightmost bits of the IPv6 address which are used to uniquely identify a network card in a host?

Interface ID

What is an IPv6 address type that indicates that the IP address was configured by default?

Link-Local

What address for the local host is 0:0:0:0:0:0:0:1 (also identified as ::1 or ::1/128)?

Local Loopback address

What is an IPv6 address type that indicates that the packet is addressed to a number of hosts on the network, but not all hosts?

Multicast

What ID is the leftmost bits of the IPv6 address, also know as the network ID?

Prefix ID

What is when clients automatically generate the interface ID and learn the subnet prefix and default gateway through the Neighbor Discovery Protocol (NDP)?

Stateless Autoconfiguration

What assignment is the entire 128-bit address and all other configuration information is statically assigned to the host?

Static Full Assignment

What assignment is the prefix statically assigned?

Static Partial Assignment

What ID is used for routing IPv6 packets?

The prefix ID

What method allows IPv6 hosts or sites to communicate over the existing IPv4 infrastructure?

Tunneling

What is an IPv6 address type that indicates the IP address is a private IP address?

Unique-Local
