addresses: [192.168.1.2/24, '2001:1::2/64']
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]

這是正確的嗎?沒有看到 gateway6: 不用嗎?請指點,疑惑中...

找到答案了

關於IPv6的設定，我並不懂，先貼一下剛找到的參考網址，
也許您研究了，您有心得，可以來分享怎麼設定，感恩先

我先從「Ubuntu Server Guide」，

找到「Networking」，

接著找到「Network Configuration」，

接著找到「netplan man page」，

然後使用「IPv6」當關鍵字，可以找到相關的說明，有您提到的「gateway6」的範例。


       addresses (sequence of scalars)
              Add static addresses to the interface in addition to the ones received through DHCP
              or  RA.   Each  sequence  entry  is  in  CIDR  notation,  i.   e.   of   the   form
              addr/prefixlen.   addr is an IPv4 or IPv6 address as recognized by inet_pton(3) and
              prefixlen the number of bits of the subnet.

              Example: addresses: [192.168.14.2/24, "2001:1::1/64"]

       gateway4, gateway6 (scalar)
              Set default gateway for IPv4/6, for manual address  configuration.   This  requires
              setting addresses too.  Gateway IPs must be in a form recognized by inet_pton(3).

              Example for IPv4: gateway4: 172.16.0.1 Example for IPv6: gateway6: "2001:4::1"




也可以執行指令下面指令，來閱讀「netplan man page」


$ man netplan



或是查詢「ubuntu 18.04 ipv6」，

查到兩篇參考文章，「1」，「2」，

裡面都有提到是參考「這篇」，對照您提供的範例，猜測您應該也是參考「這篇」。

以上提供參考，我還沒實際去測試，只是先貼出來找到的參考資料

Package: netplan.io
Description-md5: 171990596b9adbbde53590d783767a6d
Description-en: YAML network configuration abstraction for various backends
 netplan reads YAML network configuration files which are written
 by administrators, installers, cloud image instantiations, or other OS
 deployments. During early boot it then generates backend specific
 configuration files in /run to hand off control of devices to a particular
 networking daemon.
 .
 Currently supported backends are networkd and NetworkManager.

addresses: [8.8.8.8,8.8.4.4] ==> 這個是DNS吧？

兩個都是addresses:，應該有點問題。

不過這一行是ipv4的ip。

關於您提的疑問，因為顯示的時候，縮格不見了，

原本樓主的是

小王 寫到：
在網路上查到如下
ens33:
dhcp4: no
dhcp6: no
addresses: [192.168.1.2/24, '2001:1::2/64']
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]

這是正確的嗎?沒有看到 gateway6: 不用嗎?請指點,疑惑中...


我重新設定「BBCode，加入「[ code ] [ / code ]」，顯示就會有縮格。

轉成「json」的格式，如下


{
	"ens33": {
		"dhcp4": "no",
		"dhcp6": "no",
		"addresses": [
			"192.168.1.2/24",
			"2001:1::2/64"
		],
		"gateway4": "192.168.1.1",
		"nameservers": {
			"addresses": [
				"8.8.8.8",
				"8.8.4.4"
			]
		}
	}
}





應該可以解答您的疑問

可以執行「$ man netplan 」觀看最下方的「Examples」

還有可以參考「Wikipedia / YAML」，了解「yaml」的格式。

上面「#2」我有列這些參考連結。

或是也可以到「https://learnxinyminutes.com/」，找到「yaml」來參考，可以用關鍵字「a_nested_map」找尋該頁面。

以上提供參考，

報告完畢
