After enabling WPA and changing the default password and SSID, fiddling
with IP (or MAC) addressing provides, at best, only miniscule additional
security benefits that aren't worth the hassle.

As others have pointed out, shrinking the pool of addresses handed out
by the DHCP server doesn't really restrict the number of IP addresses
that can use your network. To do that, you need to alter the subnet
masks of the router and other devices. For a two-device network (a
router and one computer), you'd use a subnet mask of 255.255.255.252.
The next smallest standard subnet (with a continuous range of addresses)
you can create is for six devices with a mask of 255.255.255.248.
