Hi,
Our security manager wanted to setup some firewall rules to allow external traffic coming into the system only from known IPs. I am wondering the following list( from this url https://ppmts.custhelp.com/app/answers/detail/a_id/92 and select ipnpb.paypal.com) is a complete list for the IPs sending out the IPN, also will Paypal keep adding more IPs to the list? Thanks
173.0.84.8
173.0.84.40
173.0.88.8
173.0.88.40
64.4.248.8
173.0.92.8
173.0.93.8
64.4.249.8
