Dear Leo,

IPv4 PI Number of assignments

size	2004	2005	2006	2007	2008	2009
/16	0	0	1	0	0	2
/17	2	0	1	1	0	0
/18	3	1	2	3	10	2
/19	12	3	7	4	12	10
/20	23	25	28	23	44	23
/21	54	51	56	89	100	52
/22	236	260	260	260	399	192
/23	359	384	463	776	571	244
/24	551	724	895	972	1046	440
/25	11	9	22	8	8	6
/26	7	7	6	0	5	1
/27	7	4	8	8	7	2
/28	0	0	8	0	1	0
/29	0	2	1	0	8	0
total	1265	1470	1758	2151	2211	974

Note: Both /16 assignments in 2009 are temporary assignments that will
be returned before the end of the year.

IPv4 PI Assignment size

year	total IPs

2004	986400
2005	897744	
2006	1153800
2007	1305312
2008	1617520
2009	881536

IPv4 Allocation numbers and sizes

year	number	total size

2004	1001	37838336
2005	1143	57196544
2006	1213	59731968
2007	1333	62085120
2008	1649	44496896
2009	844	24535040

To put these numbers in perspective: The RIPE NCC assigns more
PI prefixes than we allocate as PA, while the number of IPs assigned
as PI is around 3% of the total that we assign or allocate.

The RIPE NCC does not set aside address space for PI assignments
larger than the current minimum allocation size, a /21, because these
assignments can be made from any of our IANA allocations. We do mark
some free blocks with a minimum allocation size of less than a /21 as
usable for smaller PI assignments. This list is periodically reviewed
and currently contains a bit over a /11 of address space.

If you have any questions about these numbers, please do not hesitate
to ask.

Best regards,

Alex Le Heux
