環境 ubuntu 16.04
工具 dhcp-4.3.5.tar.gz
安裝isc-dhcp
點擊下載dhcp-4.3.5.tar.gz，或到從官網下載https://www.isc.org/downloads/
編譯安裝
解壓：
tar -xvf dhcp-4.3.5.tar.gz
安裝：
cd dhcp-4.3.5
./configure
make
sudo make install配置文件
- 創建 /etc/dhcp/dhcpd6.conf 作爲配置文件：
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
subnet6 2001:db8:0:1::/64 {
# Range for clients
range6 2001:db8:0:1::129 2001:db8:0:1::254;
# Range for clients requesting a temporary address
range6 2001:db8:0:1::/64 temporary;
# Additional options
option dhcp6.name-servers fec0:0:0:1::1;
option dhcp6.domain-search "domain.example";
# Prefix range for delegation to sub-routers
prefix6 2001:db8:0:100:: 2001:db8:0:f00:: /56;
# Example for a fixed host address
host specialclient {
host-identifier option dhcp6.client-id 00:01:00:01:4a:1f:ba:e3:60:b9:1f:01:23:45;
fixed-address6 2001:db8:0:1::127;
}
} - 創建空文件 /var/db/dhcpd6.leases
配置網卡
通過命令 ifconfig 獲取當前網卡接口名稱
test@test-virtual-machine:~/dhcpd$ ifconfig
ens37 Link encap:Ethernet HWaddr 00:0c:29:30:b2:bc

配置網卡靜態IPv6地址
選擇 2001:db8:0:1::1/64 作爲 DHCP Server 的固定 IP（與 dhcpd6.conf 中的 subnet6 在同一網段即可）。
sudo ifconfig ens37 inet6 add 2001:db8:0:1::1/64
注：此處 ens37 爲上文通過命令 ifconfig 獲取的啓動Server
sudo dhcpd -6 -cf /etc/dhcp/dhcpd6.conf ens37
注：此處 ens37 爲上文通過命令 ifconfig 獲取的常見問題
如果DHCP Server啓動後，仍無法獲取IP，可以嘗試關閉ubuntu的防火牆
sudo ufw disable
重啓win7 客戶機可以獲取 IPv6 地址，但無法 ping 通 DHCP Server
因爲 isc ipv6 dhcp server 沒有下發默認網關導致，可以通過手動添加默認網關解決
