DHCP IP reservations Security

I am curious, is there any security benefits of establishing IP reservations for clients on my network, I have about 30. Such that each machine would always get assigned the same IP based on MAC address. Ive done it for the printers, and considering it for the machines, but was unsure if its a good move or if it is not good; I am trying to enhance security.

Anyone have any security or other input, thanks in advance.
