django setup allowed hosts

To setup allowed hosts in Django, follow these steps:

1. Open the settings.py file in your Django project.
2. Locate the ALLOWED_HOSTS variable in the file.
3. Set the value of ALLOWED_HOSTS to a list of strings representing the host/domain names that Django should allow.
4. Each string in the list should be separated by a comma.
5. The host/domain names can be specified using either an IP address or a domain name.
6. Wildcards can also be used to allow multiple subdomains or domain names. For example, '*.example.com' would allow all subdomains of example.com.
7. If you want to allow all host/domain names, you can set ALLOWED_HOSTS to the wildcard '*' value. However, this is not recommended for production environments due to security reasons.
8. Save the settings.py file.

By setting the allowed hosts in Django, you specify which host/domain names are allowed to access your Django application. This is an important security measure as it helps prevent unauthorized access and protects your application from potential attacks. Django will only respond to requests from the host/domain names specified in the ALLOWED_HOSTS variable.
