DHCP Lease Vs Own?

We had an interesting debate at work about exactly how DHCP works and who holds the lease / IP address.

Understanding you can set ranges for which addresses are in a dhcp pool and which are static. With that said - I would like your take of how the following would work. This may be in another discussion but was unable to find exact answer.

I have a dual NIC server set to...

** ****** ******* **** *** ****** ** ****** ****. *** client ******* ***** ** ******* ****** *** *** ****** ** longer ************ ** *** ******** ******* *** ** **** ****** / ** *****. * ****** **** ****** ** **** ** find ***** *** ******* *****. **** * **** ******* ** assigned ** *** *** **** *** ** ***** *** ****** then ** **** **** ***** ******* *** **** ** ******.

*'* ***** **** ** ********* **** *********, ****if *** **** ****** ** ********* *** **** ****** ** *** **** ******* **** ****** ** ******* ** ******, it is generally preferable to keep all devices dynamic and assign reservations to them so that changes like gateway, DNS, etc. can propagate automatically. Note the bolded text, though: if you don't have the ability to update the DHCP server, or have it updated as needed, you could run into a problem in the process of setting things up.
