![我应该使用什么 IPv6](https://linux22.com/image/756924/%E6%88%91%E5%BA%94%E8%AF%A5%E4%BD%BF%E7%94%A8%E4%BB%80%E4%B9%88%20IPv6.png)
我有多个 IPv6,我需要知道哪个有效,在我的网络上它们都可以工作,但我需要知道我的 AAAA 记录应该使用哪个。

答案1
您的计算机正在从路由器获取 SLAAC 和临时隐私地址。SLAAC 地址是固定的,基于网卡的 MAC 地址。您将使用此地址来接收传入连接。
隐私地址优先用于传出连接,这样它们就不会与您的传入连接相关联,或者当您的计算机每 6-12 小时获得一个新连接时它们彼此之间就不会相关联。
temporary
隐私地址是您输出中标识的地址ip addr
,而固定 SLAAC 地址是另一个地址,其中包含ff:fe
主机部分中间的。尽管说是,但dynamic
除非您更换 NIC 或伪造其 MAC 地址,否则它实际上不会改变。
请注意,您的路由器仍然存在影响您传入连接的防火墙问题,并且由于明显的措施似乎没有帮助,您可能需要向 IMU 寻求帮助。
