Multicast (including Broadcast) Addresses
Multicast (including Broadcast) Addresses
组播mac是指第40位为1的mac，01:00:5e:x:x:x是ip组播mac。
很多人经常把组播MAC和IP组播MAC混淆，认为只有01-00-5e开头的MAC才是多播MAC地址，这其实个误解。
Since any vendor with a vendor block, can use that for a unique multicast (group) address block, you may want to also check the vendor page if you don't find what you are looking for here.
