Ipware Python Module

The ipware module is a Python library that provides utilities for retrieving information about the client's IP address in a web application context. It includes functions for detecting the client's IP address from various sources, such as HTTP headers and the WSGI environment, and provides a consistent API for accessing this information. The module can be useful for applications that need to track or filter requests based on the client's IP address, or for logging purposes. It supports both IPv4 and IPv6 addresses, and works with popular web frameworks such as Django and Flask.

It uses a number of techniques to try and determine the IP address of the client, including looking at the REMOTE_ADDR environment variable, parsing X-Forwarded-For headers, and checking for known proxy headers.

History:

The package was first released in 2012 by Dave Hall and is available on the Python Package Index (PyPI) under the BSD license.

The motivation for creating Ipware was to provide a reliable and consistent way to retrieve a user's IP address in a web application, regardless of the various proxies, load balancers, and other intermediaries that can exist between the user and the web server.

The original version of Ipware provided three methods for retrieving the user's IP address: get_client_ip, get_real_ip, and get_ip. These methods used various HTTP headers and the remote address of the user's connection to the server to determine the correct IP address.

Over the years, the package has undergone several updates and improvements, including support for the IPv6 protocol and adding a get_client_ip_forwarded method to handle cases where a proxy forwards the user's IP address.

Ipware iIpware is widely used in the Python web development community and has been integrated into many popular web frameworks and applications, including Django, Flask, Pyramid, and Bottle.

The ipware module includes three main functions for retrieving the IP address of a client:

1. get_client_ip().
2. get_client_ip_address().
3. get_client_ip_proxy().

get_client_ip() returns a tuple containing the client's IP address and whether or not it was retrieved from a proxy. This function uses all available methods to try and determine the IP address of the client.

get_client_ip_address() returns just the IP address of the client, without any information about whether or not it was retrieved from a proxy. This function is useful if you only need the IP address and don't care about the details of how it was retrieved.

get_client_ip_proxy() returns the IP address of the client as well as any IP addresses of proxy servers that the request went through. This function can be useful for debugging or troubleshooting issues related to proxies.

Overall, the ipware module is a useful tool for any web developer who needs to retrieve the IP address of a client in a web application. It is easy to use and provides reliable results, even in complex network environments.

The ipware module is a Python library that provides a simple and reliable way to retrieve a client's IP address in a web application. Here are some of the main features and uses of the ipware module:

Examples:

Basic usage:

This will get the client's IP address from the request object. The second return value is a boolean indicating whether the address is a private IP address or not.

Using get_real_ip:

This will try to get the real IP address of the client, even if the request is forwarded by a proxy or load balancer.

Custom IP headers:

This will check the HTTP_X_FORWARDED_FOR and X_FORWARDED_FOR headers in addition to the default headers when looking for the client's IP address.

Using get_client_ip_address:

This is a shortcut for getting the client's IP address without checking for private IP addresses or using custom headers. These are just a few examples of how to use ipware

Features:

• Simple and easy-to-use interface
• Multiple techniques for determining the client's IP address, including checking the REMOTE_ADDR environment variable and parsing X-Forwarded-For headers
• Options for customizing the module's behavior, such as setting a list of trusted proxy IP addresses
• Compatible with various web frameworks, including Django, Flask, and Pyramid
• Lightweight and designed for high performance.
• Proxy detection: The module can also detect if the request has been forwarded by a proxy server, and in that case, it can extract the IP address of the last proxy server in the chain.
• IPv6 support: The module supports both IPv4 and IPv6 addresses and can extract them from HTTP headers and request objects.
• Django support: The "ipware" module has built-in support for the Django web framework. It can be used as a middleware in a Django application to extract the client's IP address.
• Flask support: The module also supports the Flask web framework. It can be used as a decorator in a Flask application to extract the client's IP address.
