[SOLVED] PayPal IPN Updates

Hi all,
I’ve received the email below from PayPal. Would you please let me know if any updates need to occur as a result? Thank you

Reminder: Important information about Instant Payments Notification (IPN)

Name,

As communicated via email in the first week of December 2020, PayPal is expanding the Instant Payments Notification (IPN) infrastructure used to notify merchants about events related to the status of PayPal transactions. This change has added seven new IP addresses from which IPNs are being sent since January 18, 2021. Below are all of the IP addresses that are being used for IPN.

66.211.170.66
173.0.81.1
173.0.81.0/24
173.0.81.33
173.0.81.65 (New)
173.0.81.140 (New)
64.4.240.0/21 (New)
64.4.248.0/22 (New)
66.211.168.0/22 (New)
173.0.80.0/20 (New)
91.243.72.0/23 (New)

Call to Action

If you are implementing any Access Control List (ACL) or filters on IP addresses for the IPNs received from PayPal, we request that you add all the aforementioned IP addresses before May 1, 2021. Doing so will help avoid missing IPNs from PayPal.

If you have any further questions about this migration activity, please feel free to reach out to Merchant Technical Support ( www.paypal-techsupport.com ).

Thank you,

PayPal

That won't have anything to do with CBSubs. That's for if you have a firewall for example setup to limit what can communicate with your server. They're providing their new IP addresses for them to be added to your exception list if you had such filtering configured on your server.

Ah excellent, thank you!
