   This was very well written, as was Carlos' reply!   
   Thanks.   
      
   Key takeaways...   
   a. If the device is set to DHCP they get what the router gives them.   
   b. But if set to static, that's it - they are that IP address.   
   c. The router can give that same IP address to some other device also.
