Live PowerShell With Karl Prosser

This uses my AS function to make the expression more declarative but basically its a wrapper around win32_networkadapterconfiguration that projects and flattens the data in a nice Pscustomobject that is easy to use in scripts and export to csv files or whatnot. I use this to do inventory on IP settings over our whole network

function get-ipinformation
{
process {
    (Get-WmiObject Win32_NetworkAdapterConfiguration -computer $_ ) | ? { $_.IPenabled } |
    select (AS Server , __server,
        DNSHostName ,  DNSHostName ,
        Mac , Macaddress,
        Description, Description,
        DNSDomain , DNSDomain,
        FirstIPAddress ,{ ($_.IPAddress) | select -first 1 },
        IPAddressAll , { [string] $_.IPAddress} ,
        IPSubnet , {($_.IPSubnet) | select -first 1 } ,
        IPSubnetall , { [string] $_.IPSubnet },
        DefaultIPGateway, { ($_.DefaultIPGateway) | select -first 1 } ,
        DefaultIPGatewayALL, { [string] $_.DefaultIPGateway },
        DHCPEnabled , { [bool] $_.DHCPEnabled },
        DHCPServer,  DHCPServer,
        PrimaryDNSServer , { ( $_.DNSServerSearchOrder)[0]  },
        SecondaryDNSServer , { ( $_.DNSServerSearchOrder)[1]  },
        AllDNSServer , { [string] $_.DNSServerSearchOrder },
        WINSPrimaryServer , WINSPrimaryServer,
        WINSSecondaryServer , WINSSecondaryServer,

        #random ones
        DomainDNSRegistrationEnabled , DomainDNSRegistrationEnabled,
        FullDNSRegistrationEnabled , FullDNSRegistrationEnabled,
        DNSDomainSuffixSearchOrder, DNSDomainSuffixSearchOrder,
        WINSEnableLMHostsLookup , WINSEnableLMHostsLookup
       )
    }
}
