Allow IP

You may allow some users to submit your form only by setting their IP addresses or address ranges.

Examples:

allow_ip = 123.45.67.8

This will allow all users with IP 123.45.67.8 to submit your form.

allow_ip = 123.45.*.*

This will allow all users with IP range 123.45.0.0 to 123.45.255.255 to fill your form.

allow_ip = 123.45.67.*, 123.55.77.88

This will allow all users with IP 123.55.77.88 and on range 123.45.67.0 to 123.45.67.255.
