大家帮忙看看，这些手机mac地址(去掉了中间的冒号)的有效性，是真实的吗？尤其020000000000这条。
------解决方案--------------------
这条看起来不像真的，应该是虚拟设备的

那个肯定不是真实的，MAC地址真实性判断的确是很难的事，只有通过抽查来判断。

Search the Public OUI/'company_id' Listing
在这个框里输入比方你提供的第一个mac的前三位：04-E5-36
可得到以下内容，得知是一个苹果设备。
Here are the results of your search through the public section of the IEEE Standards OUI database report for 04-E5-36:
04-E5-36 (hex) Apple
04E536 (base 16) Apple
1 Infinite Loop
Cupertino CA 95014
UNITED STATES
Your attention is called to the fact that the firms and numbers listed may not always be obvious in product implementation. Some manufacturers subcontract component manufacture and others include registered firms' OUIs in their products.
