-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Oh, it's the truth - trust me. There was an Interop show (back when it really was an Interoperability event) that was made quite enjoyable for the network staff by that set of NIC cards.... Chris On 05 Sep 2008, at 07.53, Scott Berkman wrote:
This reminds me of a story I was told a while back that there was a batch of 3com NIC's that all went out with the same MAC from the factory. I never found out if that was a rumor/urban legend or the truth. Anyone know firsthand or have an article about that?

Just when you thought this couldn't happen any more...
Copying from a different email list...
mac address 04:4b:80:80:80:03, was showing up in multiple places across the network. I googled the mac address and discovered that other people are having the same issue with this mac address. Below are some links describing the problem:

I just wanted everyone to know about this problem in case you run across similar slow "connectivity" issues. I believe the network card is made by NVIDIA.
