The following table shows the list of lines on this page and whether it's a valid IP address or IP address range. If the line is a valid IP address or IP address range, it will be whitelisted from CAPTCHA but invalid lines will be ignored. An example of a valid IP address range would be: 69.208.0.0/16 which goes from 69.208.0.0 to 69.208.255.255. More information about calculating an IP address range.
