Section 9 - IP Addressing Flashcards
How many address types does IPv6 have?
Unicast, Multicast, Anycast
Can multiple IPv6 addresses (including types of IPv6 addresses) be assigned to a single network interface?
Yes
How many types of Unicast IPv6 addresses exist? And what are they?
Two. Globally-routed, and Link-local
What is the range of Globally-routed IPv6 Unicast addresses?
2000-3999
What is the first segment in all Link-local/Local Use IPv6 addresses consist of?
FE80
What does IPv6 Stateless Address Autoconfiguration (SLAAC) do?
It eliminates the need to obtain addresses or other configuration information from a central server like DHCP
Which IPv6 protocols are used in conjunction with SLAAC?
EUI-64 (Extended Unique Identifier-64), and NDP (Neighbor Discovery Protocol)
What are the first two digits of the first segment of every IPv6 mulitcast address?
FF
Which segment does SLAAC insert in the center of a MAC address, which in turn it uses to form the second half (called EUI-64) of a globally-routable IPv6 address?
FF FE
SLAAC is an autoconfiguration process in IPv6
True
SLAAC is used in IPv6 to discover the current network that a network interface is located on
True
SLAAC in IPv6 Selects its own host ID (the second half of a globally-routable IPv6 address) based on its MAC address using the EUI-64 process
True
The Extended Unique Identifier (EUI) process allows a host to assign itself a unique 64-bit IPv6 interface identifier called EUI-64
True
The 64-bit EUI address is used to identify a specific interface on network
True
An EUI-64 interface uses the Auto Discovery to determine the network that it’s on, and then adds the network portion of the IPv6 address which is the first 64 bits to the front of the EUI-64 address to create a unique unicast, globally-routable IPv6 address
True
What is the purpose of the Neighbor Discovery Protocol (NDP)?
It is used to determine the layer 2 addresses that are on a given network and then pick its own host ID based on that
NDP performs router solicitations, router advertisement, neighbor solicitation, neighbor advertisement, and redirection. This is used to determine the default gateway and any devices on the network, such as printers and file servers
True
When NDP performs redirection,
True
