My name is Steve Lyons and I reside in Tampa, FL with my 3 children, wife and Frenchie. We live the typical Florida life of swimming, fishing, boating, and BBQ. I started my F5 journey as a customer in 2009 where I was first introduced to it as a "load balancer." I have since deployed and maintained all modules realizing the BIG-IP is so much more. I joined F5 in 2015 where I have made it a personal mission to educate as many people as I can so they too can take advantage of the tremendous potential of the BIG-IP.

Off the top of my head I'll be honest I am not sure. I did some research and I personally was not able to find official numbers since much of this is based on memory resources available to the BIG-IP itself. Therefor a lot will depend on platform and DNS provisioning (dedicated, nominal or minimum). With that, I can tell you one of our teams tested up to 100k zones with memory to spare. I know this is not the answer you are looking for so I will continue to try and find more official sizing information though I cannot promise it exists.
