Welcome back. In the last lecture, we talked about the ways that you can reserve a static internal IP address. In this lesson, I'm going to show you how to reserve an IP address using the console.

Now, before we get started I need to point out that in order to reserve and to manage static internal IP addresses, I need to be granted the compute.networkAdmin role. I'm logged in as the admin here so I'm good there.

As mentioned previously, you can reserve a static internal IP address before creating the resource it will be assigned to, or you can create the resource with an ephemeral internal IP address and then promote the ephemeral IP address to a static internal IP address.

In this demonstration, we're going to reserve a static internal IP address and then assign it to a resource.

To get started, I need to identify a subnet from my VPC network that I want to work with because remember, you can only reserve IPs using a VPC network. To do this, I need to go to my VPC networks page in my GCP console here. Now, what I'll do is I'll use this test VPC network down here for this demonstration.

Next, I need to go to my VM instances page where I can create my instance and reserve the IP when I create the instance. So let's browse over to our compute instances. And we'll go ahead and create our instance. I'm going to call my instance myvm, and then I'll select my regions here, along with the zone. And then from here, I need to provide the rest of the info for my instance: the size, the generation, all of that other fun stuff. I'll leave this at the default because that's not what I'm trying to demonstrate here. 

Next, I need to expand the "Management, security, disks, networking, sole tenancy" menu down here at the bottom. And then from here, I can click on Networking to edit my networking resources.

Under Network interfaces here, I need to choose the subnet that I'm reserving an address for, and then we'll select our network. Now, under Primary Internal IP here, I can choose to reserve a static IP address. But do the dropdown here, I can select reserve static internal IP address.

Now, I'll give this internal IP address resource a name. I'll just call it myinternalip. And then what we can do is we can select whether to assign an address automatically or let me choose. For this demonstration, I'll just let it assign an address and I'll reserve it. I'll leave the rest of the settings here at their defaults and just minimize this dropdown. And then from here I can click Create to create my resource. And what this is going to do is spin up a new instance that's connected to my subnet within my VPC. When it comes up, it's going to do so with a reserved static internal IP address.
