Debian 9.6 不使用接口中定义的静态 IP

我有以下配置：

root@pihole:~# cat /etc/network/interfaces
auto lo
iface lo inet loopback

allow-hotplug enp0s4
iface enp0s4 inet static
address 192.168.2.225
netmask 255.255.255.0
gateway 192.168.2.1

IP 不知为何被分配给了 192.168.2.110，但它应该是 .225：

root@pihole:~# systemctl restart networking.service
root@pihole:~# ifconfig
enp0s4: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.110  netmask 255.255.255.0  broadcast 192.168.2.255
        inet6 fe80::2a0:98ff:fe2a:67fe  prefixlen 64  scopeid 0x20<link>
        ether 00:a0:98:2a:67:0e  txqueuelen 1000  (Ethernet)
        RX packets 5322438  bytes 1348940213 (1.2 GiB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 333698  bytes 66021804 (62.9 MiB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0

有什么建议可以解释为什么会这样吗？此配置原本可以正常工作...但几天后它变为 .110。

编辑：添加“ip a”命令的输出，因为这表明IP被设置为“次要”：

2: enp0s4: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 00:a0:98:2a:67:0e brd ff:ff:ff:ff:ff:ff
    inet 192.168.2.110/24 brd 192.168.2.255 scope global enp0s4
       valid_lft forever preferred_lft forever
    inet 192.168.2.225/24 brd 192.168.2.255 scope global secondary enp0s4
       valid_lft forever preferred_lft forever
    inet6 fe80::2a0:98ff:fe2a:670e/64 scope link
       valid_lft forever preferred_lft forever
