First and foremost, PayPal recommends using DNS to determine the IP address of our servers. We change DNS often, and do not notify ahead of time. If you choose not to use DNS, you should know that at all times except during scheduled maintenance, at least one of the IPs listed below for each system will be live and serving traffic. But not all of them will be, and it is the responsibility of the end user's application to know how to cycle through all the addresses until it finds one that is working.
In Q1 2012 the IP addresses for PayPal API endpoints, svcs.paypal.com endpoint and ipnpb.paypal.com post back url will be expanded further. Please see the list of additional IP addresses at the bottom of this list, and you can read more about this upcoming change here

Zen Cart already DOES use DNS to access PayPal.

None of what you're talking about has any context nor does it make any sense. We can't help you if you don't explain the problem.

My customers get this massage :

An error occurred when we tried to contact the payment processor. Please try again, select an alternate payment method, or contact the store owner for assistance. () - (6) Couldn't resolve host 'api-3t.paypal.com'

Thanks

That's a problem on your webserver, not a Zen Cart problem.
Your hosting company will need to fix their server problem which is preventing proper name resolution.
