The BIA can be overridden with a "Locally Administered Address " (LAA). The following technologies use the MAC-48 identifier format:" So there is no such thing as local range. also you can read all the RFC's about it on http://www.faqs.org -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
