I knew I had seen 00-00-5E used somewhere. This is from RFC 2338 (http://www.faqs.org/rfcs/rfc2338.html). 7.3 Virtual Router MAC Address The virtual router MAC address associated with a virtual router is an IEEE 802 MAC Address in the following format: 00-00-5E-00-01-{VRID} (in hex in internet standard bit-order) I suppose you could use these addresses if your network doesn't use VRRP, but to me it seems like throwing rocks at a beehive. > -----Original Message----- > From: rich+ml@lclogic.com [mailto:rich+ml@lclogic.com] > Sent: Monday, August 04, 2003 9:55 PM > To: Eble, Dan > Cc: sandy pond; linux-net@vger.kernel.org > Subject: RE: Public MAC address range > > > I have it on good authority that IANA reserved this block for > private use > (in the same way that IANA reserved IP 192.168.X.X for > private use), but > can't find documentation. > > Anyway if you accidently reproduce mac address on your subnet > go to Las > Vegas immediately. :) > > On Mon, 4 Aug 2003, Eble, Dan wrote: > > > Date: Mon, 4 Aug 2003 12:28:19 -0400 > > From: "Eble, Dan" <DanE@aiinet.com> > > To: "'rich+ml@lclogic.com'" <rich+ml@lclogic.com>, > > sandy pond <sandy_pond@myrealbox.com> > > Cc: linux-net@vger.kernel.org > > Subject: RE: Public MAC address range > > > > OUI 00005E is assigned to the IANA.
