为什么只有debian返回127.0.0.1

我创建了获取本地主机和当前ip地址的代码的一部分，我在windows，linux（opensuse,debian），mac上尝试了这个，并且每个人都返回除debian之外的他的ip地址返回127.0.0.1和我连接到互联网。为什么只有debian返回127.0.0.1

因为我期待下面的地址

192.168.1.1 
192.168.1.2 
192.168.1.3 
192.168.1.4

任何帮助。

我的代码是用java编写的，并在不同的平台上测试过。

我ceraet使用inetaddress类中的Java代码

等/主机

127.0.0.1 localhost 
127.0.1.1 debiam.domain debiam 

# The following lines are desirable for IPv6 capable hosts 
::1 ip6-localhost ip6-loopback 
fe00::0 ip6-localnet 
ff00::0 ip6-mcastprefix 
ff02::1 ip6-allnodes 
ff02::2 ip6-allrouters

约SRC代码，它只是inetaddress

如果系统有多个网络接口（卡）会怎么样？如果一个接口有多个分配给它的IP地址会怎么样？ –

但我运行debian和opensuse和mac在同一台机器上都正确地返回了这个意思debian – user1344201

你还没有回答我的问题。另外你如何编程？一些源代码会很好。 –

取决于具体的实现，它将取决于您在linux中检查的接口。 lo界面会给你127.0.0.1。您可能有一个接口，如'eth0'或'eth3'，它使用您的预期IP地址。

通过这个表彰在linux

ifconfig

你把这个细节

IP 127.0.0.1是LO（回环，本地主机）接口，但在另一个接口例如eth0的你的ip是xxx.xxx.xxx.xxx或ipv6。
