用dynamicpc，日志是：
dhcpd[4574]: Added new forward map from test00.example.com. to 192.168.1.78 dhcpd[4574]: Added reverse map from 78.1.168.192.in-addr.arpa. to test00.example.com. 使用静态IP，日志是：
dhcpd[4574]: DHCPDISCOVER from c8:d3:a3:34:d1:1d (dlinkrouter) via enp2s0 dhcpd[4574]: DHCPOFFER on 192.168.1.51 to c8:d3:a3:34:d1:1d (dlinkrouter) via enp2s0 dhcpd[4574]: DHCPREQUEST for 192.168.1.51 (192.168.1.100) from c8:d3:a3:34:d1:1d (dlinkrouter) via enp2s0 dhcpd[4574]: DHCPACK on 192.168.1.51 to c8:d3:a3:34:d1:1d (dlinkrouter) via enp2s0
是否有可能使用静态IP更新正向和反向绑定映射？
