http://www.potaroo.net/ispcolumn/2003-07-v4-address-lifetime/ale.html                                                   
                      
                                                                                                                        
                      
This is actually a pretty good write-up about the IPv4 address lifetime

assigned space comparisons. Makes very good reading about all this.
