IPTool Inspect

Introduction

The inspect command of iptool allows you to analyze an IP address or a network.

You can provide the IP address in either decimal or hexadecimal format.

If a netmask is not provided, it will default to a /24 (255.255.255.0 in decimal format).

Usage

Here are the different ways you can use the inspect command:

Single IP address

These commands will inspect the provided IP address and print the details.

Dotted decimal

iptool inspect 10.0.0.1

Hexadecimal

iptool inspect c0800d25

It will also recognize addresses with 0x prepended.

iptool inspect 0xc0800d25

IP address in CIDR notation

This will inspect the address or network defined by the IP address and the CIDR prefix. The CIDR prefix indicates the number of leading bits of the network mask.

Dotted decimal

iptool inspect 10.0.0.1/24

Hexadecimal

iptool inspect c0800d25/24

IP address with subnet mask

This will inspect the network defined by the IP address and the subnet mask.

Both the IP and the mask can be in decimal or hexadecimal format.

Dotted decimal and hexadecimal combinations

iptool inspect 10.0.0.1 255.255.255.0

iptool inspect 10.0.0.1 ffffff00

iptool inspect 0a000001 255.255.255.0

iptool inspect 0a000001 ffffff00

Output

Default

By default the output of the command is pretty basic.
