IPv4 Tools PowerShell Module

Description

The IPv4 Tools module enables a set of functions to assist with common IP Address administration tasks, including :

• The ability to convert subnet masks between dotted decimal, CIDR, wildcard and binary.
• The ability to calculate the resulting broadcast, network, wildcard mask and host range based upon an entered IP address and netmask.
• The ability to validate an IPv4 address.
• The ability to generate an array of IP Addresses based on a start and end address.
• The ability to display current ARP entries.
• The ability to scan an IPv4 Range.
• The ability to scan a defined range of TCP ports.

Requirements

• PowerShell Version 4
