FWIW ISC DHCPd listens on raw sockets.

We should ban that, for security. Who needs those pesky switches anyways?

Hi Owen,
|ioctl(sock, SIOCGIFADDR, ifr)|
Shouldn't that do the trick? I don't know if Python can do that or not, but
if it can't, that's pretty weak.
As far as I was able to find out this only gives back the local MAC
address which is of no use here.
To be independent of external call I

Because it requires access to raw sockets, which should not be
necessary for DHCP?

the cat came back ... IPv4 is going away like RIP is a dead routing
protocol.
Hi,

The used SocketServer module of Python has no support for raw sockets,
as far as I see. Let me know if there is a way to get the MAC in a
cleaner way.

Hello World,
like other people we had the problem that existing DHCPv6 servers do not
evaluate the MAC address of clients, following RFC 3315. The IPv4
clients already are managed via their MAC addresses so we wanted to use
these identifiers for IPv6 too for our dualstack network.
At the end we

attempt uses the last 48bits of
