## Instructions for using Amazon VPC to create virtual networks
Amazon Virtual Private Cloud (VPC) is a logically isolated section of the Amazon Web Services (AWS) cloud where you can launch AWS resources in a private network that you define. You can use a VPC to isolate your resources from the public internet and other VPCs, and to control who has access to your resources.
To create a VPC, you can use the AWS Management Console, the AWS CLI, or the AWS API. In this article, we will show you how to create a VPC using the AWS Management Console.
### 1. Prerequisites
Before you can create a VPC, you must have an AWS account. You can create an AWS account for free.
### 2. Create a VPC
To create a VPC, follow these steps:
1. Go to the AWS Management Console and sign in to your AWS account.
2. Click the **Services** menu and select **VPC**.
3. Click the **Create VPC** button.
4. In the **Name** field, enter a name for your VPC.
5. In the **CIDR block** field, enter a CIDR block for your VPC. A CIDR block is a range of IP addresses that can be used by the resources in your VPC. For example, you can use the CIDR block `10.0.0.0/16`.
6. (Optional) In the **Enable DNS hostnames** field, select **Yes** to enable DNS hostnames for your VPC. This will allow you to use domain names to access resources in your VPC.
7. (Optional) In the **Enable DNS resolution** field, select **Yes** to enable DNS resolution for your VPC. This will allow you to resolve domain names to IP addresses within your VPC.
8. Click the **Create VPC** button.
Your VPC will be created and you will be shown a summary of its settings.
### 3. Add a subnet to your VPC
A subnet is a logical division of a VPC. You can create multiple subnets within a VPC and each subnet can have a different CIDR block.
To add a subnet to your VPC, follow these steps:
1. Go to the AWS Management Console and sign in to your AWS account.
2. Click the **Services** menu and select **VPC**.
3. Click the **Subnets** tab.
4. Click the **Create subnet** button.
5. In the **Name** field, enter a name for your subnet.
6. In the **VPC** field, select the VPC that you want to add the subnet to.
7. In the **CIDR block** field, enter a CIDR block for your subnet.
8. (Optional) In the **Availability Zone** field, select the availability zone where you want to create the subnet.
9. Click the **Create subnet** button.
Your subnet will be created and you will be shown a summary of its settings.
### 4. Connect your subnet to a route table
A route table is a collection of routes that determines how traffic is routed within your VPC. When you create a subnet, it is automatically associated with the default route table for your VPC. The default route table has a route that routes all traffic to the internet gateway for your VPC.
If you want to route traffic to a different destination, you can create a custom route table and associate it with your subnet.
To create a custom route table, follow these steps:
1. Go to the AWS Management Console and sign in to your AWS account.
2. Click the **Services** menu and select **VPC**.
3. Click the **Route tables** tab.
4. Click the **Create route table** button.
5. In the **Name** field, enter a name for your route table.
6. In the **VPC** field, select the VPC that you want to associate the route table with.
7. Click the **Create route table** button.
Your route table will be created and you will be shown a summary of its settings.
To associate your subnet with the route table, follow these steps:
1. Go to the AWS Management Console and sign in to your AWS account.
2. Click the **Services** menu and select **VPC**.
3. Click the **Subnets** tab.
4. Select the subnet that you want to associate with the route table.
5. Click the **Actions** menu and select **Edit subnet attributes**.
6. In the **Route table** field, select the route table that you want to associate with the subnet.
7. Click the **Save** button.
Your subnet will now be
