So you're saying that they are always exclusive within the lease period? Are there any routers where they aren't exclusive?

If you have configured your DHCP server to have 10 addresses available and all 10 are leased out and an 11th machine connects, it won't get an IP until one of the 10 IP's lease expires. Generally the lease time is a day or so, but could be anywhere from 10 minutes to four weeks or more.

The point--as I understand it--is to remember which address each client receives so that they can be issued the same one each time they connect as long as they connect fairly consistently. The address isn't reserved for them exclusively (within the lease time) though, is it? Meaning, if connections become sparse and are new connection attempts denied because IPs are leased to non-connected clients, or is your IP given to someone else if you're not there?
