Can I whitelist any IP addresses?

Recurly allows merchants to specify a public IP address or range within the Site Settings page that represents your computers and bypasses Recurly's fraud checks. This feature is especially useful for merchants who manually process transactions on behalf of their customers.

IP Addresses can be given in the following formats:

Single IP: 192.168.0.1

IP Range: 192.168.12.0/24 (Range must be narrower than /24).
