MAC Address of computers on same 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.

No

MAC address in unique for each computer

If you behind router then there are less changes that any one hack your computer as usually today routers has built in firewall. If not install fire wall on the systems.

There are always risks involved as you go on internet. A good antivirus and spyware programs help to protect some what

one thing is that the intruder can be able to see your router only.

From the internet what your isp or other see is your router

not any of the computers which are connected to the router.
