A question about MAC Address

Why? There's no secrets there.

You will understand that I am reluctant to post an image of my Network on an open Forum.

Your 192.xxx IP addresses are not unique.
Your 10.xxx IP addresses are not unique.
And your MAC addresses are irrelevant.
Here are my IP addresses at home:
192.168.1.103
192.168.1.104
192.168.1.107
192.168.1.111
192.168.1.114
192.168.1.115
192.168.1.120
192.168.1.131
192.168.1.137
192.168.1.149
192.168.1.165
192.168.1.170
192.168.1.183
192.168.1.189
192.168.1.209
192.168.1.217
192.168.1.225
192.168.1.226
192.168.1.227
192.168.1.243
192.168.1.249
192.168.1.254

Thank you for your replies.

I have resolved this issue, it was a problem with the Router which has now been fixed.

Thanks again

If you tell us what the router issue was then others who have similar problems in future will a have a solved thread to look at.......

Infrasonic, thanks for your reply. I am still not convinced, but according to my ISP, when the Router reboots all the local IP addresses are scrolled as part of the reboot sequence.

Therefore...... with the Network Watcher software active and visible, when I reboot the Router the display shows the 192.xxx addresses but it also shows the 10.xxx addresses and the 169.xxx addresses. All Ethernet connected devices (in this case Windows PC's) are allocated 192.xxx ; 10.xxx and 169.xxx addresses which are all shown as "Active". When the reboot has completed if I then use the Network Watcher to re-scan the Network, the Ethernet connected devices are shown to have 192.xxx and 10.xxx addresses but only the 192.xxx addresses are "Active", the 10.xxx addresses are marked as "Non-Active" and the 169.xxx addresses are removed from the list.

Still seems just a rather odd way of doing things, but I am reasonably satisfied that there isn't a real problem.
