只允许使用域网址（AWS）访问网站

Question

I have configured an instance on AWS, and am able to access my site with both of the following URLs: http://example.com and http://ec2-12-34-56-789.eu-west-1.compute.amazonaws.com .

How can I disable access to the second URL and only keep only http://example.com ?

Answer 1

When an instance is launched into a VPC, AWS provides the instance with public and private DNS hostnames if DNS hostnames are enabled for the VPC.

By default, this feature is only enabled for default VPCs and VPCs that you create using the VPC wizard in the VPC console.

Your VPC setting has this feature enabled. In order to disable it, please follow the following steps:

• Login to the AWS console
• Click on Services
• Click on VPC
• Click on Your VPCs
• Select the VPC you are using
• Click on the Action button
• From the pull-down menu, select Edit DNS hostnames
• In the Edit DNS hostnames dialog, select Yes

You may need to relaunch your instance in that VPC to remove the existing public DNS Name.
