Django IPware

A Django application to retrieve user's IP address

status-image version-image coverage-image

Overview

Best attempt to get user's (client's) real ip-address while keeping it DRY.

Notice

There is no good out-of-the-box solution against fake IP addresses, aka IP Address Spoofing. You are encouraged to read the (Advanced users) section of this page and set IPWARE_TRUSTED_PROXY_LIST to match your needs if you are planning to include ipware in any authentication, security or anti-fraud related architecture.

How to install

1. easy_install django-ipware
2. pip install django-ipware
3. git clone http://github.com/un33k/django-ipware
    a. cd django-ipware
    b. run python setup.py
4. wget https://github.com/un33k/django-ipware/zipball/master
    a. unzip the downloaded file
    b. cd into django-ipware-* directory
    c. run python setup.py

How to use

 # If your web server is publicly accessible on the Internet
 # =========================================================
 # To get the `real` IP address of the client.
 # Where:
 #    `Real IP` = an IP address that is route-able on the Internet

 from ipware.ip import get_real_ip
 ip = get_real_ip(request)
 if ip is not None:
    # we have a real, public ip address for user
 else:
    # we don't have a real, public ip address for user


 # If your web server is NOT publicly accessible on the Internet
 # =============================================================
 # To get the `best matched` IP address of the client.
 # Where:
 #    `Best Matched IP` = The first matched public IP if found, else the first matched non-public IP.

 from ipware.ip import get_ip
 ip = get_ip(request)
 if ip is not None:
    # we have an ip address for user
 else:
    # we don't have an ip address for user

 # By default the left most address in the `HTTP_X_FORWARDED_FOR` is returned. However, depending on your
 # preference and needs, you can change this behavior by passing the `right_most_proxy=True` to the API.
 # Please note that not all proxies are equal. So left to right or right to left is not a rule that all
 # proxy servers follow.
 from ipware.ip import get_ip
 ip = get_ip(request, right_most_proxy=True)
 # OR
 ip = get_real_ip(request, right_most_proxy=True)

Advanced users:

 # you can provide your own meta precedence order by
 # including IPWARE_META_PRECEDENCE_ORDER in your project's
 # settings.py. The check is done from top to bottom
 IPWARE_META_PRECEDENCE_ORDER = (
     'HTTP_X_FORWARDED_FOR', 'X_FORWARDED_FOR',  # client, proxy1, proxy2
     'HTTP_CLIENT_IP',
     'HTTP_X_REAL_IP',
     'HTTP_X_FORWARDED',
     'HTTP_X_CLUSTER_CLIENT_IP',
     'HTTP_FORWARDED_FOR',
     'HTTP_FORWARDED',
     'HTTP_VIA',
     'REMOTE_ADDR',
 )

 # you can provide your own private IP prefixes by
 # including IPWARE_PRIVATE_IP_PREFIX in your project's setting.py
 # IPs that start with items listed below are ignored
 # and are not considered a `real` IP address
 IPWARE_PRIVATE_IP_PREFIX = (
     '0.',  # externally non-routable
     '10.',  # class A private block
     '169.254.',  # link-local block
     '172.16.', '172.17.', '172.18.', '172.19.',
     '172.20.', '172.21.', '172.22.', '172.23.',
     '172.24.', '172.25.', '172.26.', '172.27.',
     '172.28.', '172.29.', '172.30.', '172.31.',  # class B private blocks
     '192.0.2.',  # reserved for documentation and example code
     '192.168.',  # class C private block
     '255.255.255.',  # IPv4 broadcast address
 ) + (
     '2001:db8:',  # reserved for documentation and example code
     'fc00:',  # IPv6 private block
     'fe80:',  # link-local unicast
     'ff00:',  # IPv6 multicast
 )

 # if you plan to use `ipware` in any authentication, security or `anti-fraud` related
 # architecture, you should configure it to only `trust` one or more `known` proxy server(s)).
 # simply include `IPWARE_TRUSTED_PROXY_LIST` in your project's settings.py
 IPWARE_TRUSTED_PROXY_LIST = ['23.91.45.15', '23.91.45.16']  # exact proxies
 # -- OR --
 IPWARE_TRUSTED_PROXY_LIST = ['23.91.45'] # any proxy within a specific subnet
 # alternatively, you may pass the `trusted` proxy list on demand on each call
 # example:  ip = get_trusted_ip(request, trusted_proxies=['23.91.45.15'])
