[address-policy-wg] 2007-08 New Draft Document Published (Enabling Methods for Reallocation of IPv4 Resources)

Dear Colleagues,

We received several questions about the IP return statistics, hence  
this followup.

These are the numbers of IPv4 addresses returned to the RIPE NCC from  
closed LIRs:
(all 2008 numbers are for the year to date)

> 2005 385024    /14,/16,/17,/18,/19
> 2006 393216    /14,/15
> 2007 1585152   /12,/13,/19,/20
> 2008 1042432   /13,/14,/15,/16,/17,/18,/19,/21

That leaves these amounts returned by LIRs that are still open:

2005 1034240	/13,/14,/15,/16,/17,/18,/21
2006 761856	/13,/15,/16,/17,/19	
2007 581632	/13,/17,/18,/19	
2008 94208	/16,/18,/19,/20	

Most of these are returned by LIRs during the evaluation an additional  
allocation
request, usually the new allocation is larger than the one that is  
returned, only
in a handful of cases is a smaller block requested.

Taking a quick manual look through our records, the numbers below can  
be used as
an indication of how much was returned voluntarily:

2005 294912	/14,/17
2006 108544	/16,/17,/19,/21	
2007 34816	/17,/21
2008 92160	/16,/18,/19,/21

To put this in context, here are the amounts of IPs allocated in total  
over the last
few years:

2005 57282560	/7,/8,/10,/11,/13,/15,/20	
2006 59914240	/7,/8,/9,/12,/15,/19,/20,/21	
2007 62181376	/7,/8,/9,/11,/12,/14,/17,/18,/20	
2008 35655680	/7,/11,/20
