Debian 网络设置被忽略

我已经浏览过互联网（和 StackExchange ;) ），但尚未找到可行的解决方案。所以（又一个）关于无效网络设置的问题 :)

我不明白，为什么我的有线接口（在此系统上称为 end0，而不是 eth0）不使用配置的静态 IP 地址（192.168.57.222），而是使用其他 IP 地址（192.168.57.45）。对于我的无线接口 wlan0（192.168.57.223），它可以正常工作。

有人可以看看我的设置和输出并告诉我哪里出了问题吗？

分配的IP地址：

~# hostname -I
 192.168.57.45 192.168.57.223 [ipv6-address]

ifconfig 的输出

接口文件为空，取消注释此处的 end0 设置不会改变行为：

~# cat /etc/network/interfaces
# interfaces(5) file used by ifup(8) and ifdown(8)

# Please note that this file is written to be used with dhcpcd
# For static IP, consult /etc/dhcpcd.conf and 'man dhcpcd.conf'

# Include files from /etc/network/interfaces.d:
#source-directory /etc/network/interfaces.d
#auto end0
#allow-hotplug end0
#iface end0 inet static
# address 192.168.57.222
# netmask 255.255.255.0
# gateway 192.168.57.1
# dns-domain my.domain
# dns-nameservers 192.168.57.6

dhcpcd.conf（无注释）。ipv6 应该可以避免我在互联网上遇到的问题。根据我对手册页的理解，nodhcp 应该“不与 dhcp 对话”，rebind 应该重新读取配置并在发生更改时重新启动服务。

~# cat /etc/dhcpcd.conf 
# A sample configuration for dhcpcd.
# See dhcpcd.conf(5) for details.
