I'm developing a custom protocol using some raw Ethernet devices and Linux. I am aware of public IP ranges (e.g. 198.168.0.0/24). Is there similar ranges for MAC addresses? I've googled and I can't find any info. The first three octets are supposed to be assigned by manufacturer. Is there some general practice for assigning MAC addresses when you don't have manufacturer codes? - : send the line "unsubscribe linux-net" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
