lo0表示loopback回环地址,就是常说的127.0.0.1的本机地址;

6to4 tunnel interface ipv6->ipv4通道接口

6to4隧道和6in4隧道都是用于ipv4到ipv6过渡时期的策略,可以使得主机或站点在其ISP(宽带运营商)并未提供IPV6服务时仍然获得访问IPV6网络的能力。但如果主机本身本不支持ipv6协议,那么隧道机制也不能使其访问ipv6。

二者的共同点是它们都通过封装的形式使用IPV4报文头对IPV6报文进行封装,并且都有封装和解封装的过程。且二者都需要一个公网IPV4地址。

不同点是:

1.IANA分配给6to4隧道的TLA部分是0x0010,和前三位001(可汇聚全球单播地址)拼接起来是2002,而分配给6in4的是0x0001,拼接后是2001。所以当看到2002:开头的IPV6地址就是6to4隧道的地址,而2001:开头的则是6in4的地址。
