There is no reason you can use the last 2 addresses unless they are taken by some other devices.

Are you subnetting 10.116.116.0 network using a 29 bit mask? If yes, 10.116.116.8 is not usable since it is a network id.

What is the subnet mask for the 10.116.116.x network?Once you know that, it will tell you which address range can it exist.
