Usage

ip_from([allowed=None], [proxies=None]) checks whether REMOTE_ADDR in the environment points to an allowed IP address. If HTTP_X_FORWARDED_FOR is set in the environment (meaning proxy access) then REMOTE_ADDR is treated as a proxy address and HTTP_X_FORWARDED_FOR as an originating IP address.

allowed optional, default - None
A list of IPs to allow access. Can be a string which is then interpreted as a single IP address
proxies optional, default - None

If a list or tuple provided then treated as a list of authorized proxy IP addresses.

If a string or unicode provided then treated as a single IP address.

Any other value - bool(proxies) == True means that all proxies are accepted

You can filter the incoming IP address:

>>> from repoze.what.plugins.ip import ip_from
>>> p = ip_from(allowed=['192.168.1.1'])
>>> env = {'REMOTE_ADDR': '192.168.1.1'}
>>> p.is_met(env)
True
>>> env = {'REMOTE_ADDR': '192.168.1.10'}
>>> p.is_met(env)
False

By default proxy access is disabled. You can enable it with proxies=True:

>>> p = ip_from(allowed=['192.168.0.0/24'], proxies=True)
>>> env = {
...     'REMOTE_ADDR': '192.168.1.1',           # proxy
...     'HTTP_X_FORWARDED_FOR': '192.168.1.5'   # origin
... }
>>> p.is_met(env)
True

And you can also explicitly specify proxies to allow:

>>> p = ip_from(allowed='192.168.1.5', proxies=['192.168.0.0/24'])
>>> env = {
...     'REMOTE_ADDR': '192.168.1.1',           # proxy
...     'HTTP_X_FORWARDED_FOR': '192.168.1.5'   # origin
... }
>>> p.is_met(env)
True
