You seem to forget that network devices use a global unique MAC address per interface. So - a 48-port blade on a Cat6K = 48 MAC addresses. Put five of those on a single chassis = 240 MAC addresses. And that's just an example. A network vendor can go thru MAC addresses faster than (many things) :) dciccaro-mac:temp dciccaro$ egrep "\s+[Cc]isco" oui.txt | wc -l 994 Divide that by two (due to the file format), multiply by 2^24 On 11/21/13 3:43 PM, Henri Doreau wrote:

These will be used by bhyve. I'm not sure where nmap gets its MAC address database, so let me know if this needs to get forwarded somewhere else.Thanks, I just updated the file with the latest IEEE data ( http://standards.ieee.org/develop/regauth/oui/oui.txt) which includes FreeBSD and about 800 other new assignments. Cheers, FyodorI'm impressed, 800 is quite a lot! Especially since AFAICS the former update was only a few monthes ago (r31386, last July). What about having your update script running every day as a crontask?
