How to ensure mobile phones and tablets get connected to the same IP

Often employees mobile devices that connect to wifi - will connect to different IP's depending where they are in the company.
This creates Leases on the server which I fear may prevent desktops and other network devices to connect to an already low IP pool on Server 2012 R2.

I realize this is not an optimum way to manage this however would it be a good start to reserve those mobile devices in the IPV4 scope in DHCP??

Everything at this point needs to be done remotely so setting up different access points with a different subnet is not an option.

Any suggestions?

First of all why your wired and wireless users are getting IP's from the same pool. You should reserve a specific network for Wireless user for example (192.168.1.0/24), If you're saying you have a Wireless controller then you can create a new IP range and active DHCP on the WLC to assign IP's from the wireless range. You can leave Windows server DHCP just for LAN users and let the WLC do that for the wireless users.
Just make sure that you have different VLAN (wired and wireless).
In case you need more details send us your network diagram showing the details.

Newer iPhones are problematic since they use random MAC addresses (in the guise of privacy) much to the bane of network administrators

useless pseudo security feature that can only be circumvented by using short leases.
