ifconfig 显示所有的网桥来自哪里？

我正在使用 Ubuntu 18.04.3 LTS

作为一名开发人员，我Docker，docker-compose和虚拟盒和流浪汉已安装

如果我在终端输入：

$ ifconfig

我得到了一长串的网络桥列表。

我不确定他们都来自哪里。

我的问题是，如果我想使用公共网络（火车、机场等），它们通常在 172.xx 上运行 -> 通常它已经被桥梁使用，所以我必须先将其关闭然后删除它，如我的所述博客

sudo ip link set br-bcc4b1218247 down
sudo brctl delbr br-bcc4b1218247

我还读到，如果您使用 Ubuntu 网络管理器，它们都可以恢复。

我试图了解它们来自哪里，但我还没有真正明白。
