Can't work with IPv6

[ruben-herold]

hi,

your code is not IPv6 save:

        if($GelfServer -notmatch "^(?:[0-9]{1,3}\.){3}[0-9]{1,3}$")
        {
            $GelfServer = [String]$([System.Net.Dns]::GetHostAddressesAsync($GelfServer)).Result[0]  
        }

        # Create a UDP client to be used to send data
        $Address = [system.net.IPAddress]::Parse($GelfServer) 
        $EndPoint = New-Object System.Net.IPEndPoint($Address, $Port)
        $UdpClient = new-Object System.Net.Sockets.UdpClient        
        ....
        $UDPclient.SendAsync($CompressedJSON, $CompressedJSON.Length,$EndPoint) | Out-Null

1. The regex did not match IPv6 addresses
2. New-Object System.Net.IPEndPoint($Address, $Port) need the right address family

Why not use [system.net.IPAddress]::Parse($GelfServer) instead of the regex?
Then check if Address is IPv4 or IPv6 and set the right address family?
