IP Addresses

This module provides a field for IP addresses. Let’s first generate an IP field:

>>> from z3c.schema import ip
>>> myip = ip.IPAddress()

Now make sure the IP addresses validate:

>>> myip.validate(10)
Traceback (most recent call last):
...
WrongType: (10, <type 'str'>, '')

>>> myip.validate('12.123.231.wee')
Traceback (most recent call last):
...
NotValidIPAdress: 12.123.231.wee

>>> myip.validate('10.0.0.1')

Since the field uses a simple function to validate its IP addresses, it is easier to use it for the tests:

>>> from z3c.schema.ip import isValidIPAddress
>>> isValidIPAddress('0.0.0.0')
True
>>> isValidIPAddress('255.255.255.255')
True

• Number of pieces failures

  >>> isValidIPAddress('12.3.1')
  False
  >>> isValidIPAddress('1.0.0.0.0')
  False
  >>> isValidIPAddress('1.0.0.0.')
  False
  

• Not integers failures

  >>> isValidIPAddress('x.0.0.0')
  False
  >>> isValidIPAddress('0x8.0.0.0')
  False
  

• Not in range failures

  >>> isValidIPAddress('-1.0.0.0')
  False
  >>> isValidIPAddress('256.0.0.0')
  False
  >>> isValidIPAddress('1.-1.256.0')
  False
