I understand perfectly what Moldova is saying, and I even agree for the most part. However, I have *proved* their DHCP service is at fault. Look at the alternative scenario of the PCs MAC address being cloned - it's perfectly feasible. As I've said before, if i plug my modem into my PC at this moment, it will not work. What I'm trying to show here is that VMs policy of just ignoring this is short-sighted and not in the interests of any of their consumers. Their DHCP service has a problem, or someone has cloned my MAC address - either way 'go away' is in nobody's interest but theirs.

and what if someone clones my PC's MAC address? where would this go then? The other thing i'm trying to show is a limitation in their diagnostic process. If it happened to me, it can happen to anyone. does anyone out there know what VMs diagnosis would be had my PCs MAC address been cloned?

All DHCP servers care, as that is how they track address assignment. Also, it is possible to manage static IP addresses via DHCP, by allocating the desired address to the user's MAC address.

Their DHCP server must have it - that's how, if you turn the device that gets the IP address off (be it PC or router), it will often get the same one back. Mine didn't change for about a year. Funnily enough, it did change whilst I was away. some co-incidence? unlikely.
Any network monitoring tool will allow you to find MAC addresses, as long as it can capture data in the same layer 2 domain as the source. The MAC address is used at layer 2 as the destination for the frame, so if that information must be available. I am the first to admit that my knowledge of cable networks is limited (OK, non-existent :-)), but at layer 3 and above, they all work the same way. I'd be stunned if VM cannot capture all the traffic that my modem passes.
This isn't a rant, BTW - it's not even really a complaint, I'm just trying to show them where they have challenges. Last time I wrote to them, they actually listened and took notice. I need all the facts first before I can do that again, but for some reason, they don't want to give me them.
