Forwarded to NANOG in the interests of wider awareness... having been

really mess up your day...
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.
