.Synopsis Get a list of the Azure Public IP addresses/subnets per region. .DESCRIPTION Get a list of the Azure Public IP addresses/subnets per region. The script scrapes the Microsoft download page to find the URL to the current Azure Public IP list xml file. Then it downloads the file to a temporary location and outputs the list of IP addresses and subnets for each region selected. .NOTES Created by: Jason Wasser @wasserja Modified: 9/9/2016 08:50:05 AM Version: 0.9999 Changelog * set Region default parameter to * so that first run actually produces output. .PARAMETER Region Enter the Azure region by name. Use the ListRegions switch to get a list of available regions by name. Wildcards are acceptable. .PARAMETER XmlFilePath Enter a temporary path to store the XML file. .PARAMETER DownloadUrl The URL has been pre-populated from the Azure documentation website. https://azure.microsoft.com/en-us/documentation/articles/backup-azure-vms-troubleshoot/#networking .PARAMETER ListRegions Get a list of the region names. .EXAMPLE Get-AzurePublicIpList -ListRegions Name ---- europewest useast useast2 uswest usnorth europenorth uscentral asiaeast asiasoutheast ussouth japanwest japaneast brazilsouth australiaeast australiasoutheast indiacentral indiawest indiasouth List the available regions by name .EXAMPLE Get-AzurePublicIpList -Region useast Location Subnet -------- ------ useast 23.96.0.0/18 useast 23.96.64.0/28 useast 23.96.64.64/26 useast 23.96.64.128/27 useast 23.96.64.160/28 useast 23.96.80.0/20 useast 23.96.96.0/19 useast 23.100.16.0/20 Get a list of subnets from region useast. .LINK https://azure.microsoft.com/en-us/documentation/articles/backup-azure-vms-troubleshoot/#networking .LINK https://gallery.technet.microsoft.com/scriptcenter/Get-AzurePublicIpList-928b0a0d #> function Get-AzurePublicIpList { [CmdletBinding()] Param ( [Parameter(Mandatory=$false, ValueFromPipelineByPropertyName=$true, Position=0)] [string]$Region='*', [string]$XmlFilePath = 'C:\Temp\AzurePublicIpList.xml', [string]$DownloadUrl = 'https://www.microsoft.com/en-us/download/confirmation.aspx?id=41653', [switch]$ListRegions ) Begin { # Establish Empty array $AzurePublicIpSubnets = @() } Process { # Scrape the Download page from Microsoft $Uri = Invoke-WebRequest -Uri $DownloadUrl -UseBasicParsing # This line is for not basic parsing, but it kept prompting for accepting the cookies. #$AzurePublicIpXmlUri = ($Uri.Links | Where-Object -FilterScript {$_.InnerText -eq 'Click here'}).href # Find the link in the download page that has the xml.
