01
Front

How many bits are in an IPv6 address?

Back

IPv6 addresses contain 128 bits.

02
Front

How is a full IPv6 address written?

Back

It uses eight groups of four hexadecimal digits, called hextets; each hextet represents 16 bits.

03
Front

How can leading zeros be shortened in an IPv6 hextet?

Back

Leading zeros in a hextet may be omitted; for example, 0db8 can be written as db8.

04
Front

What does the number after the slash in an IPv6 prefix mean?

Back

It gives the number of leftmost bits that define the network prefix.

05
Front

What prefix length is usual for an IPv6 LAN subnet?

Back

A /64 is the normal subnet size for most IPv6 LANs and is expected by many common address-autoconfiguration mechanisms.

06
Front

How does IPv6 anycast deliver a packet?

Back

An anycast address is assigned to multiple interfaces, and routing delivers a packet to one of them, typically the nearest.

07
Front

What does IPv6 multicast identify, and what range begins multicast addresses?

Back

Multicast identifies a group of interfaces; multicast addresses begin with ff and fall within FF00::/8.

08
Front

Does IPv6 use broadcast addresses?

Back

IPv6 has no broadcast address; multicast serves functions that might otherwise rely on broadcast.

09
Front

What does the IPv6 address ::1 refer to?

Back

The address ::1 is the loopback address and refers to the local device.

10
Front

What is the purpose of the fe80::/10 range?

Back

The fe80::/10 range is link-local unicast, used for communication on the same link and required for normal IPv6 operation on an interface.

11
Front

How does a host configure an address using SLAAC?

Back

With SLAAC, a host learns prefixes and other information from router advertisements, then forms its own address; Duplicate Address Detection checks whether it is already in use.

12
Front

What do the network prefix and IID identify?

Back

The network prefix identifies a network, and the interface identifier (IID) identifies an interface within it.
