IpAddressHelper

Module provides utility functions for manipulation with IPv4 and IPv6 addresses and networks

Overview

IpHelper project provides basic methods for IP address processing. It contains IPv4AddressHelper and IPv4AddressHelper classes containing methods:

• GetNumber(string ipAddress) returning uint number for IP address example: for 177.67.255.0 returns 2974023424 for 177.67.255.0/24 returns 2974023424

• GetRangeBoundaries(string range) returns low and high uint bounds for given IP address example: for 90.176.8.132/30 returns (1521485956,1521485959)

• BelongsToRange(string ipAddress, string range) returns true/false if IP address is in given range

Example of implementation

import-module SandBoxIpHelper.IPAddressHelper

function GetRangeBoundaries ($range, $siteId) {

    $bounds =@()
    try {
            $bounds = [GreyCorbel.Helpers.IPv4AddressHelper]::GetRangeBoundaries($range,$siteId)
            $bounds      = [PSCustomObject]@{
            low  = $bounds.Item1
            high = $bounds.Item2
        }
        $bounds
    }
    catch {
        Write-Warning "Error occurred Test-GetRangeBoundaries: $_"
        throw "Error occurred Test-GetRangeBoundaries: $_"
    }
}
