IPv4 Learning Tool

IP Tool is a Python-based command-line utility for working with IP addresses.

It provides various functionalities such as:

• converting binary IP to decimal IP
• determining IP class and private/public status
• calculating possible subnets
• and more.

Capabilities:

• Converting a binary IP address to a dotted decimal notation IP address
• Converting an IP address to binary
• Finding the network address from an IP address and subnet mask
• Finding the network address from an IP/CIDR notation
• Calculating possible subnetting from an IP range
• Determining the IP class and private/public status
• Displaying all information for an IP address and subnet

Installation

1. Clone this repository. git clone https://github.com/nanafox/ipv4-learning.git

Usage

To use the command-line interface, navigate to the directory containing the ip_tool.py script and run:

python ip_tool.py

Examples

Convert binary IP address to dotted decimal notation

Enter the binary IP address: 11000000.10101000.00000001.00000001
Decimal IP: 192.168.1.1

Convert IP address to binary

Enter the IP address: 192.168.1.1
Binary IP Address: 11000000.10101000.00000001.00000001

Find network address from IP and subnet mask

Enter the IP address: 192.168.1.1
Enter the subnet mask: 255.255.255.0
Network address with CIDR Notation: 192.168.1.0/24

Find network address from IP/CIDR notation

Enter the IP address/CIDR: 192.168.1.1/24
Network address: 192.168.1.0
IP Subnet Mask: 255.255.255.0

Calculate possible subnetting from IP range

Example 1 - With new prefix

Enter the IP network: 192.168.10.0
Enter the subnet mask or CIDR: 24
Enter new netmask/CIDR: 27

Base Network Address: 192.168.10.0/24
Base Network Mask: 255.255.255.0
Total Subnets Possible with prefix /27: 8
Total assignable IP Addresses per subnet: 30
First usable subnet: 192.168.10.0/27
Last usable subnet: 192.168.10.224/27
Wildcard mask: 0.0.0.255
PTR IP Address: 0.10.168.192.in-addr.arpa
PTR Network Address: 10.168.192.in-addr.arpa
Binary Subnet Mask: 11111111.11111111.11111111.00000000

Example 2 - Without a new prefix

Enter the IP network: 192.168.10.5
Enter the subnet mask or CIDR: 23
Enter new netmask/CIDR: 

Possible Number of Subnets: 512
Total Assignable IP Address: 510
First assignable IP Address: 192.168.10.1
Last assignable IP Address: 192.168.11.254
Broadcast Address: 192.168.11.255
Wildcard mask: 0.0.1.255
PTR IP Address: 5.10.168.192.in-addr.arpa
PTR Network Address: 10.168.192.in-addr.arpa
Binary Subnet Mask: 11111111.11111111.11111110.00000000

Determine IP class and private/public status

Enter the IP address: 192.168.1.1
Network Class: C
Address Type: Private

Display all information for an IP address and subnet

Enter the IP address: 192.168.10.4
Enter the subnet mask or CIDR notation: 24

Network Address: 192.168.10.0
Subnet Mask: 255.255.255.0
CIDR Notation: 24
Possible Number of Subnets: 256
Total Assignable IP Address: 254
First assignable IP Address: 192.168.10.1
Last assignable IP Address: 192.168.10.254
Broadcast Address: 192.168.10.255
Wildcard mask: 0.0.0.255
PTR IP Address: 4.10.168.192.in-addr.arpa
PTR Network Address: 10.168.192.in-addr.arpa
Binary Subnet Mask: 11111111.11111111.11111111.00000000
Binary IP Address: 11000000.10101000.00001010.00000100
Network address with CIDR Notation: 192.168.10.0/24
Network Class: C
Address Type: Private
