Wes Sayeed Wes Sayeed Setting a reservation for a computer that has a static IP is also a good way of preventing IP address clashes. I am very curious to know what software you run that requires a fixed IP address and is unable to know what that address is if that IP is assigned via DHCP. I've also never seen any application permanently tying a license to a single IP address. This is a great answer To call the the Poor-man's solution, you should explain what the more elegant rich-man's solution would be.
Sorry for the double comment, the edit button for the one above is already gone. I'm not knocking it at all. I just meant "poor-man's solution" as in it's built-in and therefore free.

Connect and share knowledge within a single location that is structured and easy to search. When setting up a network in need of static IP addresses I've come across at least two ways of doing so.
This can be helpful for example if you are often rebuilding a particular computer or constantly changing the OS or if setting a "static" IP address is cumbersome DirectTV DVR for example. Using DHCP reservations is also handy if you ever need to migrate to a new subnet.
A is the only way to set a static IP address. The device itself is configuring its own IP address; that's a static address. The terminology can vary, and it's like a static IP, but it really isn't. The proper term is a Lease Reservation. This is not like a static IP in the sense that, if there are no more addresses, and a node isn't using a reserved address, it will be given to another node if needed. I came across a really nasty case of this issue.
Some pinpad at a restaurant was set to static and then forgotten. When it was accidentally turned on, it started conflicting with a newer static assignment.
The entire network was going nuts. The pinpads wouldn't say address conflict, like a computer, but do strange things. Because of this, a conflicting static assignment could be made.
And when the old device comes back up. One time I was setting up a static IP on a printer long story and used some crazy number in the subnet to avoid "hitting" another static assignment. It's like playing battleship, in reverse. With reservations, it's like static assignments, but all the assignments are noted in one place. You don't have to run around configuring embedded devices.
Just copy paste some text and done. I do understand that reservations are still using DHCP. The client still needs to have the DHCP service running on the device. For more scale check out IPAM. Personally, I always set static IPs to networking devices so they can be easily found and managed.
