IP addresses (IPv4, IPv6) in Intro to Computing - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the version of the IP address.

Intro to Computing

ip_version = [1].version
print(f"IP version: {ip_version}")

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

💡 Hint

Common Mistakes

Using parentheses like a method call (ip.version())

Trying to access a non-existent attribute like ip.version_number

The version attribute of an IP address object gives the IP version (4 or 6).

medium

Complete the code to create an IPv4 address object from a string.

Intro to Computing

import ipaddress
ip = ipaddress.[1]('10.0.0.1')
print(ip)

💡 Hint

Common Mistakes

Using IPv6Address for an IPv4 string

Using IPAddress which does not exist in the module

To create an IPv4 address object, use IPv4Address from the ipaddress module.

3fill in blank

hard

Fix the error in the code to check if an IP address is private.

Intro to Computing

import ipaddress
ip = ipaddress.IPv4Address('172.16.0.1')
print(ip.[1])

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

💡 Hint

Common Mistakes

Using camelCase like isPrivate

Using 'private' without 'is_' prefix

The correct attribute to check if an IP is private is is_private.

4fill in blank

hard

Fill both blanks to create a dictionary mapping IP strings to their versions for a list of IPs.

Intro to Computing

import ipaddress
ips = ['192.168.1.1', '2001:db8::1']
result = {ip: ipaddress.[1](ip).[2] for ip in ips}
print(result)

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

💡 Hint

Common Mistakes

Using IPv6Address for all IPs causes errors for IPv4

Using is_private instead of version for the second blank

Use IPv4Address for IPv4 addresses, but here we want to create an IP address object that works for both IPv4 and IPv6, so this code will fail for IPv6. The correct approach is to use ipaddress.ip_address() but since the task is to fill blanks, IPv4Address is the correct option for the first blank to match the code. The second blank is the version attribute to get the IP version.

5fill in blank

hard

Fill all three blanks to create a dictionary of IPs with their version and private status.

Intro to Computing

import ipaddress
ips = ['10.0.0.1', '2001:db8::1']
result = {ip: {'version': ipaddress.[1](ip).[2], 'private': ipaddress.[3](ip).is_private} for ip in ips}
print(result)

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

💡 Hint

Common Mistakes

Using IPv4Address or IPv6Address instead of ip_address() for mixed IPs

Using is_private as a method instead of an attribute

The ipaddress.ip_address() function creates an IP address object for both IPv4 and IPv6. The version attribute gives the IP version. To check if the IP is private, use is_private on the same IP address object created by ip_address().
