Notice from PayPal: "Configure your firewall settings..."

I received this notice from PayPal for each of the Advanced setups I have. I don't see where it affects me but I wanted to make sure. There doesn't seem to be any hard coded IP addresses in the WA included files that I can find. Is there anything I should be doing here?

Here is a copy/paste of the email.

"As part of our on-going commitment to provide a more robust service, Payflow will be introducing additional IP addresses to both the production and pilot environments. To minimize potential impact, we recommend that you use Domain Name Service (DNS) host names instead of hard-coding Payflow IP addresses.

However, if you must allow particular IP addresses through your firewall or proxy servers, please review our list of Payflow IP addresses to ensure that the appropriate IPs are configured in your firewall/proxy settings before mid-October 2017."

Thanks,

You should be fine. We use host names instead of IP addresses, so I think you can just ignore this message.

Thanks for the confirmation on this. I figured this was not an issue but I wanted to make sure.
