How to Configure IP Address on Ubuntu using Netplan

Netplan Configuration files will be available under /etc/netplan/ directory, all these files should be only created in yaml syntax.

There will be a default yaml file and the content will be like this below.

Under ethernetes: you can specify each interface names and their network details. If you want to have dynamic ip, then dhcp4 should "yes", if you want static ip address then we must change dhcp4 value to "no". and manually you can specify the ip address,subnet,netmask and all

Lets see how to write these network configuration using netplan yaml files and how to get help of netplan examples.

This netplan manual page has lot of informations about all the options with examples where we could find options like, dhcp4, dhp6, gateway4, gateway6, nameserver, addresses, etc,.

$man netplan

Get some examples and related options as per your requirement and make changes on the network yaml files.

Once the changes are modified, Apply the changes.

Netplan has two options, netplan try and netplan apply.

netplan try - this command will help you to check syntax error and will give some options with timeout to proceed or not.

netplan apply - this command will apply the changes.

Both command can be used. Once the changes are applied, make sure to see the output of "ip a" or "ifconfig" command and try to reach the ip address configured from other system over the network.
