That script is made for RMM using like Solarwinds MSP, NinjaRMM or others.
First, the script gets the gateway's IP address :
$LocalIP = (Get-WmiObject Win32_NetworkAdapterConfiguration | Where-Object {$_.IPEnabled}).DefaultIPGateway
Then, with the IP address, the script gets the MAC address of the gateway :
$MacAddress = ((Get-NetNeighbor -IPAddress $LocalIP).LinkLayerAddress)
And the public IP address with opendns.com :
$PublicIP = ((Resolve-DnsName -Name myip.opendns.com -Server resolver1.opendns.com).IPAddress)
Next, we got arrays containing the MAC addresses by manufacturer :
$MacFreebox = "F4-CA-E5","00-07-CB","00-24-D4","14-0C-76","34-27-92","68-A3-78","70-FC-8F","8C-97-EA","E4-9E-12"
$MacLivebox = "00-37-B7"
$MacApple = "BC-B8-63"
$MacXiaomi = "E0-CC-F8"
The script cuts the MAC address of the gateway by 3 groups (bytes) :
$MacSplit = $MacAddress -split "-"
$MacPrefix = $MacSplit[0] + "-" + $MacSplit[1] + "-" + $MacSplit[2]
Next, compares the MAC addresses with arrays :
if($MacFreebox -contains $MacPrefix)
{$Router = "a Freebox"}
elseif($MacLivebox -contains $MacPrefix)
{$Router = "a Livebox"}
elseif($MacApple -contains $MacPrefix)
{$Router = "an Apple device"}
elseif($MacXiaomi -contains $MacPrefix)
{$Router = "a Xiaomi device"}
else # If router is unknown
{$Router = "Unknown"}
And give the result of the comparison :
if ($Router -like 'Unknown') # In the case router is unknown
{Write-Host "Router is unknown ($MacAddress). Maybe a randomized MAC address" ; exit 1}
else
{Write-Host "Gateway is $Router ($MacAddress). `nLocal IP is $LocalIP. `nPublic IP is $PublicIP." ; exit 0}
