Comments on: The Future of the MAC address http://itknowledgeexchange.techtarget.com/itanswers/the-future-of-the-mac-address/ Fri, 24 May 2013 12:30:07 +0000 hourly 1 By: labnuke99 http://itknowledgeexchange.techtarget.com/itanswers/the-future-of-the-mac-address/#comment-52520 labnuke99 Fri, 28 Mar 2008 13:26:53 +0000 #comment-52520 Thanks for the link/reference. It does sound like there is a plan to go to EUI-64 addresses to cover the risk of running out of 281,474,976,710,656 addresses. The EUI-64 is part of the IPv6 plan according to the referenced article. So, they (IEEE and manufacturers) have thought through this issue.

Presumably he ran the numbers — I know I didn’t!

But hypothetically speaking, If we did run out, what would happen?? Besides, word on the streets says even with that number of addresses, we’ll be running out by 2100.
