Is RT-AC86U a dynamic router?

I Have an Asus RT-AC86U router that I have no need for so i want to sell it. A potential buyer asked me the following questions but I don't know the answer to the questions. Any help would be appreciated

"Is it a dynamic router and could I connect it to my main router as a second router and have a different IP Address? "

Is the answer to these 2 questions a yes or a no?

Thanks.
