Dear Colleagues,
Hm... Is there statistics which shows subnet size requested per user for last year? Something like (actual numbers is just an example!):
Size Requests in 2006
4-32 addresses 5,000 10% 33-64 addresses 8,000 12% ... 256-511 addresses 50,000 44% ... 2048-4095 addresses 1,300 6% 4096-8191 addresses 750 3% ...
In my opinion AW can be auto-rised to almost match most "popular" assignments sizes. All further risings(lowers) can be done upon LIR request. If stats does not show clear peak - AW size can be aligned to nearest bigest value.
We have prepared statistics showing the size of all approvals that the RIPE NCC has made in 2006: Size Number of approvals 1 - 1 [/32]: 3 0.1% 2 - 2 [/31]: 3 0.1% 3 - 4 [/30]: 60 1.0% 5 - 8 [/29]: 359 6.2% 9 - 16 [/28]: 308 5.3% 17 - 32 [/27]: 220 3.8% 33 - 64 [/26]: 217 3.7% 65 - 128 [/25]: 274 4.7% 129 - 256 [/24]: 1394 23.9% 257 - 512 [/23]: 789 13.6% 513 - 1024 [/22]: 705 12.1% 1025 - 2048 [/21]: 596 10.2% 2049 - 4096 [/20]: 371 6.4% 4097 - 8192 [/19]: 191 3.3% 8193 - 16384 [/18]: 125 2.1% 16385 - 32768 [/17]: 63 1.1% 32769 - 65536 [/16]: 62 1.1% 65537 - 131072 [/15]: 37 0.6% 131073 - 262144 [/14]: 19 0.3% 262145 - 524288 [/13]: 16 0.3% 524289 - 1048576 [/12]: 5 0.1% 1048577 - 2097152 [/11]: 4 0.1% Total number of PA approvals: 5821 Total number of /21 and smaller: 4928 84.6% We hope these statistics are useful, please let us know if you need more information.
