isp-dhcp-server，ipv6，警告：主機聲明是全域的。它們不限於您聲明它們的範圍

曹，這很奇怪。一切正常，但我無法分配靜態 ipv6 地址。

您需要將主機聲明移到子網聲明之外：

subnet6 2001:470:1f1b:5b3::/64 {
       range6 2001:470:1f1b:5b3::1000 2001:470:1f1b:5b3::ffff;
       range6 2001:470:1f1b:5b3::/64 temporary;

       option dhcp6.name-servers 2001:470:1f1b:5b3::20,2001:4860:4860::8888,2001:4860:4860::8844;
       option dhcp6.domain-search "patrikx3.tk","corifeus.tk";   
}
host linksys {
       host-identifier option dhcp6.client-id 00:02:03:09:05:05:60:38:E0:10:A7:EB;
       fixed-address6 2001:470:1f1b:5b3::1;
