IPv6 addressing basics in Computer Networks - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to show the total number of bits in an IPv6 address.

Computer Networks

An IPv6 address is [1] bits long.

Drag options to blanks, or click blank then click option'

A64

B128

C32

D256

💡 Hint

Common Mistakes

Confusing IPv6 length with IPv4 length.

Choosing 64 bits because of subnetting.

An IPv6 address is 128 bits long, which allows for a very large number of unique addresses.

2fill in blank

medium

Complete the code to identify the number of hexadecimal groups in a full IPv6 address.

Computer Networks

A full IPv6 address consists of [1] groups of hexadecimal digits separated by colons.

Drag options to blanks, or click blank then click option'

A8

B4

C16

D32

💡 Hint

Common Mistakes

Confusing the number of groups with the number of bits.

Thinking each group is a single hexadecimal digit.

An IPv6 address is divided into 8 groups of 4 hexadecimal digits each, separated by colons.

3fill in blank

hard

Fix the error in the statement about IPv6 address shortening.

Computer Networks

In IPv6, consecutive groups of zeros can be replaced by [1] to shorten the address.

Drag options to blanks, or click blank then click option'

A::

B:

C...

D--

💡 Hint

Common Mistakes

Using a single colon instead of double colon.

Using ellipsis or dashes which are invalid.

The double colon (::) is used once in an IPv6 address to replace one or more consecutive groups of zeros.

4fill in blank

hard

Fill both blanks to complete the IPv6 address format with network and interface parts.

Computer Networks

An IPv6 address is divided into a [1] part and an [2] part.

Drag options to blanks, or click blank then click option'

Anetwork

Bhost

Cinterface

Dsubnet

Attempts:

💡 Hint

Common Mistakes

Confusing 'host' with 'interface' in IPv6 terminology.

Using 'subnet' instead of 'network' for the first part.

An IPv6 address consists of a network part that identifies the network and an interface part that identifies the device on that network.

5fill in blank

hard

Fill all three blanks to complete the IPv6 address representation with prefix length and zero compression.

Computer Networks

An example IPv6 address is [1]::[2]/64, where [3] indicates the network prefix length.

Drag options to blanks, or click blank then click option'

A2001:0db8

B1

C/64

Dfe80

Attempts:

💡 Hint

Common Mistakes

Using an incorrect prefix length like '/128' for typical subnetting.

Not using zero compression correctly.

The address '2001:0db8::1/64' shows a typical IPv6 address with zero compression (::), the interface identifier '1', and the prefix length '/64' indicating the network portion.
