To create VCN using the Console:

1.Open the Console.Open the navigation menu. Under Core Infrastructure, go to Networking and click Virtual Cloud Networks.

2.Choose a compartment you have permission to work in (on the left side of the page).If you're not sure which compartment to use, contact an administrator.

3.Click Create Virtual Cloud Network.

4.Enter the following:

(a)Name: A friendly name for the VCN. It doesn't have to be unique, and it cannot be changed later in the Console (but you can change it with the API).

(b)Create in Compartment: Leave as is.

(c)Create Virtual Cloud Network Only: Make sure this radio button is selected (the default).

(d)CIDR Block: A single, contiguous CIDR block for the VCN. For example: 172.16.0.0/16. You cannot change this value later.

(e)Use DNS Hostnames in this VCN: If you want the instances in the VCN to have DNS hostnames (which can be used with the built-in DNS capability in the VCN), select the Use DNS Hostnames in this VCN check box. Then you can specify a DNS label for the VCN, or the Console will generate one for you. The dialog box automatically displays the corresponding DNS Domain Name for the VCN (<VCN DNS label>.oraclevcn.com).

(f)Tags: Optionally, you can apply tags. If you have permissions to create a resource, you also have permissions to apply free-form tags to that resource. To apply a defined tag, you must have permissions to use the tag namespace.If you are not sure if you should apply tags, skip this option (you can apply tags later) or ask your administrator.

5.Click Create Virtual Cloud Network.

The VCN is then created and displayed on the Virtual Cloud Networks page in the compartment you chose.
