<pre class="literalblock">
Checks if field's value is an IP version 4 address in decimal form. Can
be set to force addresses from certain range.
IPv4 regex taken from: http://regexlib.com/REDetails.aspx?regexp_id=1411
Arguments:
minip: lowest allowed address; accepts:
str, eg. 192.168.0.1
list or tuple of octets, eg. [192, 168, 0, 1]
maxip: highest allowed address; same as above
invert: True to allow addresses only from outside of given range; note
that range boundaries are not matched this way
is_localhost: localhost address treatment:
None (default): indifferent
True (enforce): query address must match localhost address
(127.0.0.1)
False (forbid): query address must not match localhost
address
is_private: same as above, except that query address is checked against
two address ranges: 172.16.0.0 - 172.31.255.255 and
192.168.0.0 - 192.168.255.255
is_automatic: same as above, except that query address is checked against
one address range: 169.254.0.0 - 169.254.255.255
Minip and maxip may also be lists or tuples of addresses in all above
forms (str, int, list / tuple), allowing setup of multiple address ranges:
minip = (minip1, minip2, ... minipN)
| | |
| | |
maxip = (maxip1, maxip2, ... maxipN)
Longer iterable will be truncated to match length of shorter one.
Examples::
#Check for valid IPv4 address:
INPUT(_type='text', _name='name', requires=IS_IPV4())
#Check for valid IPv4 address belonging to specific range:
INPUT(_type='text', _name='name',
requires=IS_IPV4(minip='100.200.0.0', maxip='100.200.255.255'))
#Check for valid IPv4 address belonging to either 100.110.0.0 -
#100.110.255.255 or 200.50.0.0 - 200.50.0.255 address range:
INPUT(_type='text', _name='name',
requires=IS_IPV4(minip=('100.110.0.0', '200.50.0.0'),
maxip=('100.110.255.255', '200.50.0.255')))
#Check for valid IPv4 address belonging to private address space:
INPUT(_type='text', _name='name', requires=IS_IPV4(is_private=True))
#Check for valid IPv4 address that is not a localhost address:
INPUT(_type='text', _name='name', requires=IS_IPV4(is_localhost=False))
