AWS Amplify - How can I get a new IP address?

Question

Hi,

I am currently facing an issue with the IP address given by AWS. I am hosting my custom domain on Amplify.

I recently found out that I was put on a SpamHaus list after my web link was flagged as suspicious on LinkedIn.

I dug into the problem and found that this IP address: 
Network 18.165.128.0/18 had previous activity that had been involved with phishing / trying to take account information. I believe I was assigned a faulty IP address with a negative history.

I believe this is the cause for my issues, and has resulted in my not being able to use other platforms (like Mailchimp & other email providers) as my domain associated with this address doesn't meet compliance requirements.

I would like to be removed out of that network range. I have tried contacting support, with not much help. They suggested I post here.

Thanks in advance.

AWS Amplify does not provide a way to directly change the IP address for a custom domain that you have configured with your Amplify app. The IP address associated with your custom domain is managed by AWS and can change dynamically.

However, here are a few points regarding custom domains with AWS Amplify:

1. When you configure a custom domain in Amplify, AWS creates and manages the required DNS records and routing to map your domain to the Amplify hosting environment.

2. The IP address that your custom domain resolves to is essentially the IP address of the AWS CloudFront distribution that Amplify provisions for your app's hosting.

3. This CloudFront IP can change over time as AWS manages and updates their infrastructure behind the scenes.

4. You cannot directly configure or change the IP address associated with your custom domain in Amplify. It is dynamically assigned by AWS.

If having a static IP address is a hard requirement for your use case, then AWS Amplify may not be the best solution. You would need to explore other hosting options like:

- Using an Elastic Load Balancer (ELB) or Amazon Lightsail instance with a static IP assigned.
- Hosting your app on an EC2 instance with an Elastic IP.
- Using a third-party hosting provider that offers static IP addresses.

However, these options add complexity and likely additional costs compared to the fully managed Amplify service.

In most cases, the dynamic IP addressing used by Amplify's CloudFront distributions should not cause any issues, as modern DNS resolvers and clients handle IP changes gracefully. But if you have specific requirements around static IP addresses, you may need to look beyond Amplify.

If you are still facing this issue, I would consider filing an AWS abuse report as well about the resource in question & the appearance of that IP you were provisioned on the SpamHaus list. This should help you get traction with support.

You can also recreate the domain, which will give you a new CloudFront CDN with it's own new IP. This is not ideal but an option.
