mac-address

I have my website, and it records the number of visitors, IP and time of access... I want to identify each visitor... I think that this was possible recording IP Address... but when the IP is dynamic, my system fails. So I think that I can solve it recording MAC address... is possible? What language should use? PHP, ASP, Javascript? Thanks Edit: What I can use to identify each user without having login information (username & pwd). The MAC address, by TCP/IP standards, is never communicated outside of the local-area network to which it pertains -- routers beyond that LAN don't even get the

I'm looking for a solution to find out about the MAC number of a user using asp.net website. I know you can get an IP address (don't know why but it can't be complicated) but can i find out the MAC address having the IP? Edit: I mean programmatically (not manually) in .NET If your site is trusted, you can do this in IE: http://www.devarticles.com/c/a/JavaScript/Advanced-JavaScript-with-Internet-Explorer-Retrieving-Networking-Configuration-Information/1/ I wouldn't expect it to work for any typical visitors, just users who's systems you already control, like on your local network. There may be

Pre Marshmallow my app would obtain it's device MAC address via BluetoothAdapter.getDefaultAdapter().getAddress(). Now with Marshmallow Android is returning 02:00:00:00:00:00 . I saw some link(sorry not sure where now) that said you need to add the additional permission <uses-permission android:name="android.permission.LOCAL_MAC_ADDRESS"/> to be able to get it. However it isn't working for me. Is there some additional permission needed to get the mac address? I am not sure it is pertinent here but the manifest also includes <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION

Background I'm trying to get obtain a unique identifier out of a computer and want to be able to reliably return the same MAC address each time. Trust me I have my reasons for using MAC address and have read many posts about alternate unique id methods (and yes i've considered if they don't have any network cards). Problem The problem is in .NET i don't see anyway to tell whether a specific NetworkInterface is a physical hardware network card from something like a "Nortel IPSECSHM Adapter - Packet Scheduler Miniport" which get added when you connect to certain VPNs or WiFi networks. I know how

How do I get the MAC-Address of the network interface of an android device which doesn't have a Wifi-Interface (e.g. the android emulator)? WifiInfo obtained via the WifiManager returns null . EDIT To be more clear: I have to communicate with an existing network protocol (not designed by me) on the local network where I have to send the mac address of the communicating interface within the payload during a registration phase. Read /sys/class/net/[something]/address as a text file But it's unlikely to be useful in the way you think. I'm going to take a leap and assume that you want this MAC
