本文详细解释了0.0.0.0与127.0.0.1这两个IP地址在计算机网络中的不同作用。0.0.0.0通常用于指示所有未指定的主机和网络，作为本地网络配置的默认网关，而127.0.0.1则是本地回环接口的专用IP地址，仅用于主机内部的网络通信。

0.0.0.0与127.0.0.1的区别：

127.0.0.1 is normally the IP address assigned to the "loopback" or local-only interface. This is a "fake" network adapter that can only communicate within the same host. It's often used when you want a network-capable application to only serve clients on the same host. A process that is listening on 127.0.0.1 for connections will only receive local connections on that socket.

0.0.0.0 has a couple of different meanings, but in this context, when a server is told to listen on 0.0.0.0 that means "listen on every available network interface". The loopback adapter with IP address 127.0.0.1 from the perspective of the server process looks just like any other network adapter on the machine, so a server told to listen on 0.0.0.0 will accept connections on that interface too.

在非服务器端时，0.0.0.0表示：

1、所有不清楚的主机和目的网络。这里的“不清楚”是指在本机的路由表里没有特定条目指明如何到达。
2、对本机来说，它就是一个“收容所”，所有不认识的“三无”人员，一律送进去。
3、如果在网络设置中设置了缺省网关，那么Windows系统会自动产生一个目的地址为0.0.0.0的缺省路由。
