Try calling the ISP listed in the website and if you are (very) lucky. You can persuade the CSR by giving out their name or address. If you only can get the email address or username, that's good too, you might be able to contact the person and have him/her reveal their physical address.
This is a feature called “Smart Addresses”, which hides the full name and email address from view, which can help to reduce screen clutter, but for some users it can lead to erroneously sending an email to the long address, since the email address isn’t clearly shown in the To, CC, and BCC sections. Delete email addresses from Mac Mail history. If you have a contact that recently changed their main email address, or who uses a different email address for work than from home, then you probably have a reason to send emails to that person to very specific email inboxes, like I do. Now, you can change your current MAC Address to a new one by following the format of your current address (12 characters total), and changing the numbers and letters. You may arbitrarily use letter combinations from A to F, and any numbers. Hi, Physical address refers to the address that comes with the device itself and that remains permanent for a device. It cannot be changed. For example the MAC(Medium Access Control) Address is a physical address.
Somewhere I have read that both physical address and MAC address are the same,which is exactly the same attached with the NIC of a machine. And also in some other place I have read that a router is forwarding data packets based on the information such as Physical and Logical addresses available from a data packet. I have the knowledge that a MAC address will never go beyond the LAN's gateway. Then how come the other routers collect the information regarding my MAC address from a data packet send by me?
Am I supposed to believe that physical address is different from MAC address when comes into networking?

Physical address and MAC address are indeed the same.They are used to communicate between devices on Ethernet networks.When you send a request to a remote host's IP address (access a website for instance) your computer sends that request to your LAN's gateway (your router) and it uses its physical (MAC) address as the destination of the message but the logical (IP) address of the host for its final destination.The router then forwards that message onward and knows who to return the reply to.

Physical and MAC addresses are the same, just different naming conventions. Each device should have a unique MAC address assigned by its vendor. The logical addressing is the IP address assigned to interfaces.
Physical addressing/MAC addresses work on Layer 2 and Logical addressing works on Layer 3. Let's use an example to demonstrate.
Let's say PC_A wants to send something to PC_B. PC_A will create an IP packet with Source IP of PC_A and Destination IP of PC_B. That IP packet will be encapsulated in an Ethernet frame with Source MAC of PC_A and Destination MAC of R1.
PC_A sends the frame to R1 and R1 deencapsulates the frame. R1 checks the destination IP and matches it to its routing table and sees that R2 is the way to go. So R1 creates a new frame with Source MAC of R1 and Destination MAC of R2. R2 performs the same steps and eventually sends the frame to PC_B.
During this entire proces the Frame changes, whilst the IP packet remains untouched.

You might have confused with Hw add and physical address. Basically, if you consider a router/switch with multiple ports. Paint program for mac. The device will have a Hw address then each of the interfaces will have a physical address. look at the output below. You generally see this in the devices supports L3 switching.
The application to having different address is out of scope here.

Can someone give me some pointers on picking up the user's MAC address from an HTTP request?
The users will be from outside my network.

It depends on your network setup. But probably no.
Here is a short refresher on Ethernet and IP. The MAC address is a unique address of the network card. It is used to identify for which user on the network segment a packet is. You can use ARP to get a MAC address for an IP address. But this works as expected only if you are on the same network segment.
Free screen recording program for mac. So the question is, what is a network segment? It depends on the technology you use, but here are the common cases. An entire wireless network is a network segment. Every user on the network can talk via Ethernet to every other user. On wire based networks, this depends on the hardware. If you have good old BNC or a hub you have one network segment with all uses. Again each user can talk to any other. With a switch in the network a network segment is only cable that connects you to the switch. Here you can only talk to the switch via Ethernet. Every other user needs at least IP.
Too bad that most situations with HTTP, which builds on TCP/IP, you are 99.99% never in the same network segment as your user. You can use ARP, but will only get the MAC address of the first hop. It get's better, depending on your hardware, you may not even be on an IP network that is based on Ethernet; ATM for example..

Review free program for ripping dvds on mac. I don't think there is a way to do it in ASP.NET.
MAC is a property of a TCP packet, and on HTTP level there're no packets or MACs (for example, a single HTTP request might be assembled of several TCP packets).

You could try using a packet sniffer (like WireShark) to capture TCP packets, and then analyze them to extract MACs and map them to HTTP requests.
Anyway, you won't get any useful data unless the user is in the same network segment as your server. Serial key crack.
UPD. As was pointed out in the comments, I mixed up the network layers.MAC address is a property of Ethernet frame, not a TCP packet.
The conclusion is still correct, however.

This is not possible, unless you intend to create an ActiveX component, in which case it will only work on IE.
