As a highly valued Super User, I suggest you revisit this answer and add more detail. I also note that link only answers go stale, and editing your answer to reflect some of the information on the sites makes for better, more relevant answers for future users. – Journeyman Geek Jul 25 '12 at 8:24
@JourneymanGeek: You are of course correct. Except that this post is much too general to merit such an undertaking. My answer really means "learn before asking". I have voted to close this as not constructive. – harrymc Jul 25 '12 at 8:51

Yes, you can configure a router with dynamic IP address. The router will get an external IP address from the modem - which can be static or dynamic, and set up a network with a different range for its clients - which are independent and use one of the three local address blocks.

You will only need a static IP address if you wanted to run a server, and not use dynamic DNS. In your scenario, a dynamic IP address will work with no issues whatsoever.
