IP tĩnh trên Ubuntu Server thì netplan sẽ có cấu hình như thế nào?

Trong quá trình cài đặt Ubuntu Server từ file ISO, bạn hãy gán IP tĩnh cho nó như sau:

Sau đó bạn chui vào /etc/netplan để coi file cấu hình netplan ở dạng YAML có mặt mũi ra sao

# cat /etc/netplan/50-cloud-init.yaml
# This file is generated from information provided by the datasource.  Changes
# to it will not persist across an instance reboot.  To disable cloud-init's
# network configuration capabilities, write a file
# /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg with the following:
# network: {config: disabled}
network:
    ethernets:
        ens32:
            addresses:
            - 192.168.71.129/24
            nameservers:
                addresses:
                - 192.168.71.2
                - 8.8.8.8
                - 8.8.4.4
                search: []
            routes:
            -   to: default
                via: 192.168.71.2
    version: 2

Địa chỉ IP tĩnh trên Ubuntu Server thì lệnh ip a sẽ không có chữ dynamic.
