      dhcp4-overrides:
        route-metric: 100

      dhcp6: no
      addresses: [192.168.0.21/24]
      nameservers:
        addresses: [192.168.0.1, 8.8.8.8]
      access-points:
        "network_ssid_name":
          password: " **********"
      routes:
          - to: default
            via: 192.168.0.1

```

**シングルインターフェイスにマルチアドレス付与**

```auto
network:
  version: 2
  renderer: networkd
  ethernets:
    enp3s0:
     addresses:
       - 10.100.1.38/24
       - 10.100.1.39/24
     routes:
