How other IP of AWS not own by me is redirecting to my Application server's IP.

First I suggest you create a support case to ask for help.

Secondly, from my experience , It seems that we can't stop others from pointing their domain names to our site. but we can change ourselves and strengthen our own safety and logic awareness , do some things to increase website security and reduce harm.

Check your website for the following problems, may be helpfull for you :

1. After the WEBSERVER (such as: IIS, NGINX, TOMCAT, Apache) general server configures the WEB environment, some people use the root directory to make websites, and some people use the default page to throw it there. If someone resolves the server IP, they can open and see the root directory content. So don't build your own site under the default page path. Instead, create an empty HTML page and refer to 5 for configuration.

2. There is no special application to cancel or close the full wildcard domain name and empty binding, but bind the host to whichever domain name is used, which is safer. The general domain name should also usually be in the form of: *.youname.com.

3. If you can contact the owner of the domain name pointing to your IP, you can ask him to cancel the resolution, or notify the unknown domain name pointing to your IP address as a malicious service provider or operator pointing to you, as long as you don't connect to the binding. It usually has nothing to do with you, don't worry.

4. .htaccess redirect (only apache environment can use htaccess file)

   RewriteEngine On RewriteBase / RewriteCond %{HTTP_HOST} !^www.youname.com$ [NC] RewriteRule ^(.*)$ http://domain name to be redirected/$1 [L,R=301]

5. Direct meta redirect (create an empty index.html file in the default root path for editing)

<meta http-equiv="refresh" content="0; url=www.youname.com">
