Username must be unique. Password must be a minimum of 6 characters and have any 3 of the 4 items: a number (0 through 9), a special character (such as !, $, #, %), an uppercase character (A through Z) or a lowercase (a through z) character (no spaces).
A Windows OS can give you the MAC address of any machine reachable via NetBIOS by using nbtstat, even across multiple router hops. Again, nbtstat and arp are useful for getting MAC addresses for other computers.
There are also 3rd party conversion tools… where you input a mac address and it gives you the ip. Or ip –> mac.
You may be able to use manageable routers to find out where a particular ip/mac address is being used as well.
