running out of addresses?

We have a Linksys router behind a DSL modem. The router automatically
assigns DHCP numbers. the range is 192.168.1.x. With the wireless
networking I've added recently, (access point) I'm about to pass 10
computers on the network. Will the auto-assigned numbers run out at 10?
Sorry if an elementary question, but I'm in unfamiliar territory.

The router has a Admin Screen called DHCP. At the DHCP Screen not only
does one tell the router to use DHCP, but one also tells the router at
what IP the the DHCP IP(s) are to start at and how many DHCP users can be
on the router or the number of DHCP IP(s) that can be issued by the
router. Those DHCP IP(s) are also know as the programmable IP(s) of the
router, because on the other Admin Screens one can tell the router to do
something with those programmable IP(s).

Some people like to limit the number of DHCP IP(s) that can be issued by
the router to the number of physical machines wired and wireless that can
be used on the network, which kind of a security feature that can be used
by someone to prevent the wireless side from being *hacked*.

This is a no-brain security feature as someone who wants to *hack* your
network could find details about your network in a very short amount of time
using a sniffer - then just use one of the network IP addresses not being
used by your network at that moment. The IP address is passed in the clear
even when using WEP.

I use fixed IP for equipment that is setup to be permantly on the network -
servers, routers etc - and DHCP for workstations. This is no more secure -
just easier to maintain.
