以太网框架，源地址
作为源地址始终是单个地址（单次），最少 重要的第一字节总是0。
我看到了这个经验。在geeksforgeeks.com上，所以我想问一个源地址是否必须单播。我了解一个源地址是一个单独的地址，但是广播呢？即使它具有单独的MAC地址，也不是一个单播。作为第二个问题，为什么最不重要的第一字节总是0是0，而与源地址始终是单个地址有什么关系？谢谢。
As Source Address is always an individual address (Unicast), the least
significant bit of first byte is always 0.
I saw this exp. on geeksforgeeks.com, so I want to ask that whether a source address has to be unicast or not. I understand that a source address is an individual address but what about broadcasting? Even if it has an individual MAC address, it is not unicasting. As a 2nd question, why is the least significant bit of first byte is always 0 and what does it have to do with source address being always an individual address? Thanks.
