No, the MAC address of my server is available to machines on my
local LAN, and perhaps the first ISP router at their end of a DSL
line or cable modem. It is *NOT* available to most machines on the
internet. The MAC address *your* computer sees for most every
machine on the internet is likely to be the closest router of your
ISP, or that of a router in your home. If you have a dialup modem
line, you might not see a MAC address at all.
However, it probably doesn't matter. In order for the code to check
the MAC address to be run on the server, it has to be in unencrypted
form on the server. So whatever encryption you use, you also have
to include the key.
>Mac addresses are NOT useful for security.
Definitely agree here. You can easily change your MAC address to be
anything you want.
