MAC == 000000000000. Is it possible???

[Igor I. Shulz]

ARP tables for one of the hosts in my network (GSP-card for rp8400 server) holds
xxx.xxx.xxx.xxx 000000-000000

I see this value in ProCurve switch's arp-table and in any other host in the network too. Is it really possible? Or this is some fake?

Thank you,

In my company this can happend when some fresh developer forgets to configure beta version "white mode" device.

Hmm...

Sorry, what is 'white mode' ?

"white mode" it's when there's a software being tested (in my case software is router's/switch's operating system) vs "black mode" when there's a device.
someone during those tests should manually assign MAC address.If he forgets -you can find such entries in ARP table.
