How many Public DHCP IPs in Bridge Mode with Dynamic IP?

​I've asked this before [1] but I'm looking to see if I can get a definitive count or answer.​

​If I have a Comcast Business modem with Bridge Mode and plug in multiple routers into the modem with DHCP assignment, each router will pull a different public dynamic IP address. That's working as intended, but I wanted to know how many such devices can I pull public IP addresses for? If I plug a switch in, can I get as many dynamic public IP assignments as routers or will there be a limit? I'm not looking to abuse the service, but wanted to know whether I can count on any specific number.​

@GARDEN. That is a great question! I have checked my references and there is nothing about a limit. I will see what I can find and get back to you.

Thank you for your patience @GARDEN . We have done some research, and I am not finding a specific answer to provide you. It looks like this question is account specific (depends on the plan you have). I would like to take a closer look at your account. We can circle back around to the public Forum once we have an answer. Can you send us a direct message? To do so follow these steps.
