需要帮助！我想在我的 Raspbian PI 中创建一个 AP。我选择 dnsmasq 作为 dhcpv4 和 dhcpv6 服务器。但是，我的笔记本电脑可以成功获取 IPv4，但无法获取 IPv6。为什么 dnsmasq 不适用于 IPv6？

答案1
您在配置中犯了几个不同的错误。首先，站点本地地址已被弃用多年。任何告诉您使用以 开头的地址的文档fec0都已过时，需要更新。
站点本地地址的替代品称为唯一本地地址。这些地址由fd第一个八位字节和五个字节组成。随机的八位字节。例如，您可以将fdda:772b:1c61::/48其作为本地前缀。
但是，上述两种类型的地址都不适用于要与自己网络之外的任何设备通信的计算机。如果希望这些计算机与自己网络之外的任何设备通信，则应从 ISP 路由给您的前缀中为它们分配地址。
此外，对于许多场景来说，使用 DHCPv6 并不是最佳选择。这取决于您的特定需求，但通常使用路由器广告守护程序（例如radvd）比 DHCPv6 服务器更合适。
