Module 2 Unit 3

True or False Is ::/128 a valid unicast host address?

False

What is an EUI-64 and how might it be used by IPv6?

Extended Unique Identifier (EUI) is IEEE's preferred term for a MAC address. EUI-64 is a 64-bit hardware interface ID. A 48-bit MAC address can be converted to an EUI-64 using a simple mechanism. The EUI-64 can be used as the IPv6 interface ID, though a randomly generated token is often preferred.

True or False Is fe80::219:d2ff::7850 a valid unicast host address?

False

True or False Is ff02::219:d2ff:fea7:7850 a valid unicast host address?

False

What type of IPv6 unicast address is not routable?

Link-local address (and Unique Local addresses (ULA).

In IPv6, how could you distinguish a unicast address with global scope from other addresses?

Starts with binary "001" or hex "2" or "3".

In IPv6, how can a client obtain a routable IPv6 address without requiring manual configuration?

Stateless Address Autoconfiguration (SLAAC) allows a host to autoconfigure an interface by listening for Router Advertisements to obtain a network prefix.

What is 6to4?

A method of tunneling IPv6 packets over a IPv4 network.

What is anycast?

A special type of multicast where a message can be sent to any member of a group (the closest available one) but not all of them.

Convert the binary value "1010 0001 1000 1100" to hex

A18C

If assigned a single global IPv6 address prefix, how many bits are available for subnetting?

16 Bits

In IPv6, how is the loopback address best expressed?

::1

True or False Is fe80::218:8bff:fea7:bd37 a valid unicast host address?

True
