IP Address Changes to Website Payments Pro? Payflow?

I've just had an email about some changes to Paypal Website Payments Pro - I don't think these changes effect Zen Cart but it would be much appreciated if someone in the know could confirm. The email I received includes the below text which is the bit I'm not 100% about:

To ensure your Website Payments Pro transaction processing resumes appropriately post-migration; please check your integration and/or network configuration. If your integration and/or network configuration has hard coded PayPal’s IP addresses, please go to https://www.x.com/view-blog-post.jspa?blog=1983&blogPost=4500 for more information on the new IP addresses, the planned data migration of our applications, and the scheduled migration timelines. These dates and times are subject to change, so please be sure to regularly monitor the referenced blog.

If you're using the latest version of Zen Cart, you can ignore that email since the required integration steps have already been taken, in both the Website Payments Pro (US, UK, Canada) integrations and the Payflow Pro (addon) integrations.

Thanks DrByte! Your help is much appreciated. I'm actually currently on v1.3.9b - is this OK regarding the issue mentioned?

Thanks again,
Dave

Yes. All versions of Zen Cart have always used the named DNS resources, and not specific IP addresses.

No changes required.

Thanks again DrByte! Really appreciated.

PayPal will be sending more mass emails tomorrow to all Payflow merchants and Website Payments Pro Payflow Edition (UK) merchants with the same notification.

Zen Cart is already protected, and requires no special changes to ensure uninterrupted payment operation.

Just wanted to say "Thanks Dr. Byte!!"
I came here first to see what to do, and saw your post here.
Thanks for being on top of it!
