There are a couple of options, but they depend on the capabilities of
your router. You'll need to log on to it (http:// and then the address
of the "Default Gateway" as given by the ipconfig command in a command
prompt).
You need to avoid the router handing out an address which is already
assigned to the PC - that way madness lies...
1) If you have the option to extend the length of the lease of an
address, that can be enough. Longer the better for your situation.
Then the router simply remembers that the PC had address xyz recently,
and gives it out again. Many routers allow this.
2) You can assign a fixed IP address to the PC, but it's only safe to
do this if you can tell the router only to issue addresses (the "scope")
in a range which doesn't cover the fixed IP you've set. Many routers
allow this.
3) Best overall, if you router will do it: some DHCP servers (your
router is doing this) allow you to reserve specific IP addresses for
specific devices, recognised by their "MAC" address (letters and numbers
separated by colons, usually). Your router may conveniently list
"attached devices" (alias "clients" and other terms) in which case it
will usually tell you their MAC addresses. Alternatively, ipconfig /all
will give you the MAC address (as "physical address"). Then the router
will always dish out the same address (you specify it) to the same bit
of kit. Most routers don't do this, sadly - it's really useful!
