MAC Address of 5 computers on a network

[dwright]

At home I have 5 computers on a network which all access the internet via a router.

My ISP is Pipex and they provide a Dynamic IP address (I turn the router on and off each day to change the IP Address.

Will all of these 5 computers have the same MAC Address?

If this is the case, is it possible for intruders to recognise that the 5 computers are on the same network? Thanks in advance.

From anyone outside of your network, it will appear as they have the same MAC address. Routers, when they get information, replace the mac address of the source or destination with the routers own network
