网卡IP和网关IP不在同一网段，为什么还能访问外部网络？

Question

各位大大，望解惑

信息如上所示，网卡IP和网关IP不在同一网段。

那进行外部访问的时候，数据走到网关172.31.159.253之前是不是还要经过在同一网段的交换机？或是通过其他方式连接至网关172.31.159.253？具体是什么逻辑呢

Answer 1

你确定它们不在一个网段吗？！

请注意那个“子网掩码”，它可是 255.255.240.0！

如果还没懂就请再复习一下子网及子网掩码的知识点吧

Answer 2

当我们需要让Git去管理某个新项目/已存在项目的时候，就需要创建仓库了。注意，创建仓库时使用的目录不一定要求是空目录，选择一个非空目录也是可以的，但是不建议在现有项目上来学习Git，否则造成的一切后果概不负责！
注意：为了避免在学习或使用过程中出现各种奇葩问题，请不要使用包含中文的目录名（父目录亦是如此）。
