Depending on specific installation, usually the DHCP lease time is set high enough that you'd have to not be using your computer for a rather long time to get assigned a new address. <div>On 2/1/06, Bob Nielsen <<a href="mailto:nielsen@oz.net">nielsen@oz.net</a>> wrote:<blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> On Feb 1, 2006, at 5:46 AM, Dave M G wrote: Possibly if you reboot your computer the router will assign a different address. Some routers permit you to tie an IP address to the MAC address of your computer's network interface which would avoid this. Alternately, you can assign a static IP to your computer (preferably outside the range of those assigned by DHCP) by using the network configuration tool or editing /etc/network/interfaces. </blockquote> </div>
