MAC addreses identify (in theory) a NIC uniquely (worldwide)... so these provide among other things the ability to recognize a computer even when it is using dynamic IP address...
As it is a best practice to minimize any exposure of data my recommendation would be the other way around: Is it absolutely necessary to expose this piece of data in this specific case ?
From what you describe I don't see any benefit but potential harm... so: don't expose any MAC unlesse absolutely necessary.
In the past, the mac address was used in the calculation of GUIDs. That actually has led to capturing the author of a virus that contained such a GUID. So yeah, for him it was harmful.
显然，如果你能轻易隐藏它，那就这么做吧。 但总的来说，这并没有任何真正的危害，今天，在 Linux 上使用一个简单的命令，您就可以更改您的 MAC 地址。在网络中，任何人都可以是任何人。
Oviusly if you can easly hide it do it. but in general there isn't any real harm, today with a simple command on linux you can change your MAC addr as it.seen ny the network, as anybody could be anybody.

MAC 地址（理论上）唯一地（全球）标识一个 NIC...因此，即使计算机使用动态 IP 地址，这些地址也提供了识别计算机的能力...
因为这是最大程度地减少任何暴露的最佳实践data 我的建议是相反的：在这种特定情况下是否绝对有必要公开这段数据？
从你的描述来看，我没有看到任何好处，但有潜在的危害......所以：除非绝对必要，否则不要暴露任何 MAC。

过去，Mac 地址用于计算 GUID。这实际上导致捕获了包含此类 GUID 的病毒的作者。所以是的，这对他来说是有害的。
