Is there a way to identify a client by MAC address when using the 
Vibe library?
The `NetworkAddress` 
[structure](https://vibed.org/api/vibe.core.net/NetworkAddress) 
does not provide such features. Or did I miss something?

That doesn't have anything to do with the server side if I am not 
mistaken as you should receive that via the browser that actually 
allows you to receive the mac address -via an extension- or some 
private API exposed by the browser.

I don't know the use case but you may be better off with browser 
fingerprinting if you'd like to have a unique way of identifying 
the visitors. Or, if it's a local network, maybe you can use 
tcpdump/libpcap.

It is at the packet level to monitor the address. Not at all what 
I would like. Thanks for the tip:)

Mac is a hardware address. By the time the packets get to your 
server, that info is long gone. Even if you could get it, it 
likely is the MAC address of your router, not the peer.

You are right, information is lost at the packet level and 
nothing reaches the browser anymore. I will look for another way. 
Thanks!
