mac 上的 ifconfig 查看多出来了很多网卡，这是怎么回事？？

[uuair]

查看 ifconfig 的时候，多出来很多网卡，而且 google 上我没有搜索到答案啊（中文 google ），这是怎么回事？能删么？怎么删？

我知道开了 6to4 那个，会获得 ipv6 的地址，但我这个是内网的吧？而且怎么这么多个？？其他的呢？？？ 因为现在开机上网速度很慢，我觉得会不会跟这个网卡的事情有关系所以来问问。

我的网络配置如下：

ifconfig 命令如下：

觉得多的话你可以删掉。点你发的图里左下角的 “-” 就可以了。

[torbrowserbridge]

和虚拟机，翻墙软件有关系貌似

[oovveeaarr]

不会噢

[molvqingtai]

en0 是你的本机网卡

[becareofzm]

你这个是开虚拟机了

[uuair]

@ysc3839 那个可以删啊？


@torbrowserbridge 我只有 surge。虚拟机用的是 parallels，但我没开啊。刚安装了一个 Crossover，难道跟这个有关系？

@becareofzm

[torbrowserbridge]

@uuair surge 估计也会创建虚拟网卡

[ysc3839]

@uuair 你用不到的都可以删。
