Type the 'ifconfig' command from a terminal window.

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.
